"What are you talking about it?" "Why?" "I hit him first" "And I held him so he wouldn't move" "Don't even think about it" "No way" "You were in your room" "You didn't see anything Got it?"

"Mang-won district near Han river Dead body found, calling for back-up" "Hey guys" "That head is like a rotten watermelon" "Do you think you'll get something?" "Look here" "The fingerprints are destroyed" "It might take up to 2-3 weeks to identify the body" " 2-3 weeks?" " Yes" "What kind of lunatic did this?" "The asshole grinded the body to hide the victim's identity" "The killer is an acquaintance Perhaps, the closest person to the victim" "So what?" "We can't even ID the victim What good does that do?" "What now?" "Are you going to fool around until forensics come out?" "The face is smashed so badly I don't think we can match a dental record" "I don't know if you can ID the body" "You're really good at making people feel worse" "That's a real talent" "Don't step around there" "This is going to suck" "The only thing we have is the body with two balls" "The disposal of the body seems too timid to be a psychopath's job" "The tires are all flat Is it abandoned?" "Lift that" "Is that a key?" "JINSUNG Inn" "Guess the bastard was in a real hurry to make a mistake like that" "He didn't pay and left his stuff" "I was going to call the police" "Have you seen any visitors?" "No idea" "There are so many who come and go" "The victim is 36 year old male living in Daejeon" "The name is Kim Cheol-min" "It's fortunate you found it" "The victim was staying in a motel just before the murder, since November 7th" "Luckily, we found the motel key at the scene" "The DNA from the hair in the motel matched the body's DNA" "Cause of death?" "According to the autopsy, he was killed by strangulation" "We found a consistent pattern of an electric wire used in heating devices on the victim's neck" "We analyzed it as the electric wire often used in irons" "Irons?" "Estimated time of death?" "We estimated it as November 9th in between 4 P.M. and 11 P.M." "So the victim was walking alive before 4 P.M. on the 9th" " Correct?" " Yes" ""to be exact, he was alive till 736"" "Based on what?" "We found an abandoned self-service rental bicycle on the scene" "Self-service bicycles?" "You can easily rent the public bicycles by entering your resident registration number" "It was rented from a kiosk in Sang-am district" "It was rented with Kim Cheol-min's resident number" "Really?" "So you have a suspect?" "Considering the travel path and radius," "Kim Cheol-min's ex-wife, Baek Hwa-sun is our prime suspect" "The reason is?" "Now, we need to find out" "Thank you" "Kim Cheol-min was found dead" "He was brutally murdered" "We had some trouble locating you because your address was changed" "According to the registration files, he doesn't have any relatives" "Do you know of any distant relatives?" "I don't think he has any" "I see" "When did you meet him last?" "I haven't seen him since I moved to Seoul" "You haven't talked to him during the recent months?" "No" "If you don't mind what did you do on the 9th?" "Pardon?" "November 9th" "I worked" "And after you got off?" "I took my niece to a movie" "Guess it was a nice outing for a change" "What's wrong with your hands?" "What?" "Your hands..." "I got hurt at work" "When?" "A few days ago" "Hello" "It's me from next door" "The detectives were here this afternoon" "I did as you told me" "Ok. they're coming for Yoon-ah soon" "Okay" "What did you do to it?" "How did they find out so quickly?" "Did they find the body?" "Just answer like a machine only to the questions asked" "They might be watching you from near" "So even if we bump into each other, act like usual neighbors" "I'll warn Yoon-ah also" "Did you tell them about the movie tickets?" "No" "You told me not to show them until I was asked" "Where did you put the tickets?" "In my wallet" "No, no" "The movie flyer, fold it in half and put the tickets inside" "Not many people keep movie tickets" "They might get suspicious if you take them out from your wallet" "Okay" "I will" "I'll always call you around this time" "I was wondering..." "Yes?" "If we really should do this" "You have to trust me" "Alright" "The only family she has is her niece" "She wanted to live out her sister's dreams" "She was going to raise Yoon-ah for her sister" "It is so sweet of her I admire her" "So she left town" "Did Kim Cheol-min come here recently?" "About a week ago" "He went crazy here trying to get Hwa-sun's whereabouts" "So did you tell him where she was?" "Are you insane?" "What did he do this time?" "Is he in trouble again?" "He was murdered" "Whoever did it, I am grateful" "Hwa-sun will finally get some sleep at night A real good sleep" "Thank you" "You said you saw a movie with your niece on November 9th" "Do you have the tickets by any chance?" "Pardon?" "The movie tickets" "No, I don't" "Oh" "I have this though" "Movie tickets" "For November 9th" "You saw this movie?" "Detective Jo, what's with you?" "Why are you keep insisting Baek Hwa-sun is the killer?" "She has a clear motive for murder" "And her hands It's due to strained ligaments" "You saw the scar on victim's neck" "When you choke someone to death with a thin wire, you will get a sprain" "That's a coincidence" "There's no such thing as a coincidence to a detective" "Isn't it too perfect to find tickets in between a flyer from the recycling bin?" "What's wrong with perfect?" "When are you going to become a real detective?" "From now on, it's about who cracks down first" "Put out the cigarette" "Let me warm up with it" "No" "It's cold" "Turn off the engine, idiot" "What's wrong with you, stupid?" "Baek Hwa-sun" "I think the cops are watching right now" "Here" "Isn't that the guy who went in first?" "I think so" "Pizza" "Movies" "It's all here" "How did you end up watching a movie with your aunt?" "You're in middle school Don't you have a lot of friends?" "Guess you're very close to your aunt" "She listens well too, right?" "She'll do whatever her aunt tells" "Anybody can use a credit card" "I didn't use her card She never gave it to me" "Really?" "So your aunt used it?" "Yes" "Thanks for the drink" "What is wrong?" "Wait" "What are you doing?" "Excuse me..." "You...?" "Cheers" "I can't believe I ran into you here this is so weird" "It's good to see you" "Hey, do you remember... the woman living next door to you" "That case I told you earlier" "She's the prime suspect" "She has an alibi but an alibi is there to be broken" "It could be" "Okay" "Get in" "Alright." "See you later" "Okay" "Oh!" "Doped out Pythagoras!" "Right?" "Right, right" "It's been a while Doped-gores" "It was good to see you" "What happened?" "What did you tell the detectives?" "They're probably still here" "Here." "Act natural as if taking something from me" "Get inside" "She was looking out the window the whole time" "As if she was waiting" "Of course" "The guy next door was talking to a cop who thinks you're a suspect" "Must be really nervous" "I ran the credit card" ""She bought the tickets exactly at 7:52"" "So you believe Baek saw the movie" "And on Kim Cheol-min's phone record" "He ordered some Chinese on the 9th and nothing else" "He has never talked to Baek" "Ok. think of it this way" "The niece could've swiped the card and says she didn't" "Even if Baek went there herself, there is plenty of time" "But there's no proof that she didn't see the movie" "Don't you dare look at me like that" "So this is all about that..." "Goldbach's conjecture" "Go where?" "Goldbach, stupid" "Like right now, there is suspicion but no evidence" "It will drive you nuts" "Did you get anything from your school friend?" "Seok-go" "Nothing interests him except for math" "Math?" "Have you ever seen a genius?" "It's not divisible, it's a prime number" "Yo, Kim Seok-go" "Doped-gores" "So you're a genius?" "What are you going to do with your genius brain?" "Prove" "Prove?" "Prove what?" "Have you ever heard of Goldbach's conjecture?" "No way" "So go on" "Every even integer greater than 2 is the sum of two primes" "True or false?" "Nobody has solved it in 300 years" "What do you think?" "True" "Then it's done Do you must prove it?" "If I don't prove it, I won't know the truth" "I want to know the truth" "The truth" "You want to find the truth" "By the way, making a problem no one can solve or solving that problem" "Which is harder?" "You prove that How would I know?" "Here." "Lilac is the taste of love, true?" "Prove that, say "ahh"" "Good" "If you want to prove it, chew it well" "That is love, dude Bitter, huh?" "We went to high school together" "It's an unexpected variable but it's going as calculated" "Don't worry" "But you need to be more careful about such actions" "I'll trust you completely from now on" "Did the cops question Yoon-ah?" "Yes." "She said they were waiting outside the school" "Can you get Yoon-ah on the phone?" "Hold on" "Hello" "What did the cops ask you?" "They showed me a picture and asked if I've met him recently" "I told them I haven't" "They asked again about going to the movies" "What did you tell them?" "I said I saw the movie on the 9th for sure" "And I told them about my friend I ran into at the movies" "Good. that's good, Yoon-ah" "And one more thing" "If they come again, don't be scared Just do as you're doing now" "Okay, Yoon-ah?" "I will" "Things are really happening as he said" "Surveillance tapes from the theaters" "Oh my head the moment finally has come" "Don't be intimidated" "Just watch the elevator camera" "Detective Jo" "Baek Hwa-sun" "Did they come?" "The two came They did come to the theaters" "So the friend story is true" "Then..." "I just need to find Baek leaving alone" "They indeed saw the movie" "Guys" "What's wrong with you?" "What are you doing?" "Shouldn't you be asking around Kim Cheol-min's acquaintances?" "Money problems, women problems Middle, high school friends" "People from military service Co-workers" "You" "Don't go looking for motives Go find people with motives" "Got that?" "Got that?" "Answer me!" "Yes, sir!" "Captain" "What, now what!" "They want me to take the lie detector test tomorrow" "I don't think I can do it anymore" "I should've turned myself in that day" "I think it will be better to turn myself in right now" "What would happen to Yoon-ah then?" "No." "Just do as you've been doing" "You don't have to lie" "Don't worry about that" "I don't know what's going on" "Why is everybody asking about the 9th?" "You don't need to know" "The cops will soon find another suspect" "You said you trusted me" "that I'll protect you no matter what" "I do I trust you" "Tomorrow will be the last crisis" "Please lift the sleeve on your left arm" "I have a lot of appointments today So let's do this quickly" "Don't be nervous" "From now on, answer "no" to my questions" "Are you a man?" "No" "Is your name Baek Hwa-sun?" "No" "Good." "We will start now" "Has Kim Cheol-min ever come to your workplace?" "Have you ever met Kim Cheol-min at your workplace?" "No." "I have not" "You said you saw a movie on November 9th Is this true?" "Yes" "Did you watch the movie from the beginning to end?" "Yes" "Did you meet your ex-husband, Kim Cheol-min on November 9th?" "Meet him?" "Yes." "On November 9th, did you meet Kim Cheol-min?" "No." "I did not" "You didn't see him?" "Not even once that day?" "No" "There's no need to continue with the next question" "Thanks for your time" " Is it over?" " Yes" "Wait, you skipped an important question!" "Ms. Baek Hwa-sun" "Did you kill Kim Cheol-min?" "Did you kill him?" "Who the hell are you?" "No." "I didn't kill him" "It's a lie" "What are you doing?" "It says it's a lie" "You're not an examiner I won't accept this" "Wait, don't turn it off!" "Ask her one more time" "Baek Hwa-sun." "Did you kill Kim Cheol-min?" "We won't be seeing you anymore Get home safely" "Hey, Sang-joon" "Come on." "Man..." "It went well as you said" "Okay, you did good" "Let's eat" "Why doesn't he call?" "It would be nice if he joined us" "I didn't think about that" "Yoon-ah" "I'm sorry" "Why?" "I'm really super grateful to you Every single day" "Yoon-ah, promise me" "You have to forget everything" "You have to go on" "Alright." "Don't worry" "Can I eat now?" "Yes" "Hey" "You saved them, right?" "What?" "My flowers" "I know everything" "Hey" "You like my aunt That's why you helped us, right?" "I wanted to thank you And my aunt waited for your call" "Yoon-ah" "Here's your order I'll help you with the bill" "Thank you" "Enjoy your meal." "What can I get you?" "Sunshine Morning Lunchbox, please" "Sunshine Morning?" "Thank you." "Enjoy your meal." "Good Morning Lunchbox to go?"

"Okay" "I understand" "Dude." "Who killed you?" "Dude!" "Stop, stop, stop!" "She passed the polygraph" "And the polygraph said she killed him" "The examiner said anyone would do the same if you ask with that look" "Look here, compare them to the other people" "Do they look like they're enjoying an outing to the movies?" "I know you don't want to accept" "Are we going on a stakeout?" "Welcome" "Hey, Hwa-sun" "I went to Daejeon the other day and heard the news from Madam Jung" "Did the cops come see you?" "They came a few times" "I was worried that you might be harassed for no good reason" "I'm alright" "If there's anything I can help" "No." "It's ok You've been helpful every time. thank you" "It's raining" "I'm alright" "No." "You might catch a cold" "Woo-hoo!" "Who are you and where have you been?" "Take care." "I'll call you later" "No." "I don't think..." "I regretted letting you go like that" "I won't do that anymore" "Get in" "Auntie, it's him calling" "Hello" "Was everything okay today?" "Yes" "Who was the man you came with?" "I know him from where I used to work in Daejeon" "I see" "He loaned me some money before" "He came to see me and I couldn't just make him leave" "So we had tea" "You don't have anything else to say?" "Then I'll call you tomorrow" "What's wrong?" "It's nothing" "Hey, drenched Doped-gores!" "Where have you been?" "Look at all these books here" "Look at these, you're hopeless" "This math formula..." "It's sickening" "You truly are doped out Pythagoras" "Did you find the killer?" "No." "I'm totally screwed" "Why?" "Your next door neighbor She really screwed me up" "I must be getting old" "I was pretty good back in the days but now I'm a big mess" "I'm looking for another suspect, but don't know where to look" "Where is that fucker?" "A mustache" "Look at all these old notes" "What is this?" "Nothing." "I was bored" "Hey, this is Goldbach's conjecture" "Are you still working on this?" "Are you not going to drink?" "I sure am" "Are you getting some progress with this conjecture?" "Right. that's why no one has proved it in several hundred years" "This is difficult, conjecture..." "You're right" "My brain is getting dull, It's getting difficult" "If I fail to prove it, I'll ask when I get up there" "What?" "Up there." "He will know the truth" "Whether Goldbach's conjecture is true or false" "In the most beautiful and simplest proof" "You, a philosopher Drink up" "Hey, Seok-go Are you seeing anyone?" "You?" "I've been married for 3 years" "Also, it's been a year since I got divorced" "Ugh, I really truly don't get it" "You know what my wife said when she left me?" "She left a famous line" "Do you know what love is?" "She asked me that" "She implied that I never truly loved her" "But shit. think about it What is true?" "what is real?" "What the fuck is real love?" "Shit" "You said love is bitter" "What?" "You said Love is bitter" "When did I say that?" "Li..." "Lilac!" "Right?" "You remembered that?" "You're a mathematician" "Doped-gores is smart" "I am so jealous of you, Kim Seok-go" "You are awesome doing all this math" "This is what's real." "Mathematics" "What the heck is the Perfect Number?" "I'll never forget your care." "Thank you" "Are you up?" "Yeah hey, last night..." "Why did I drink so much last night?" "I didn't do anything weird, did I?" "I feel really shitty" "Good luck on your test Are you coming straight home after school?" " Yeah, see you later" " See you" "GOOD MORNING Take-out" "You still go to this place?" "Didn't I tell you?" "I always buy my lunch there" "Don't you feel awkward?" "Eating lunch prepared by a murder suspect?" "Though you wouldn't care about something like that" "I'm going to wash up" "I think I'm sobering up It's getting cold." "Go under?" "Okay under" "Aren't they cold?" "It's not summer anymore" "These people here are always the same like clockwork" "So I've heard they are precise like a clock" "We're always fast or slow living life in a hurry" "If we free ourselves from clocks, will we be more punctual?" "Who is he staring at?" "Bye" "Hey" "Aren't you going to pick up lunch?" "You have to eat" "Hello" "No, no, no." "I'm not a cop today I came as a customer" "Okay" "Let's see." "What should I get?" "What are you getting?" "He always orders Good Morning Lunchbox" "Okay then, two Good Morning Lunchboxes, please" "Okay" "Hey." "Did you find out?" "Hold on" "Sorry but do you have a piece of paper?" "Okay." "So what?" "Hold on" "Sorry. the pen isn't working" "Choi Chan-min?" "010-3413" "728... 7287 87 Correct?" "87?" "Okay, be right over" "Thank you" "Welcome" "Hello Mr. Nam, you came again" "Here you go" "How much is it?" " It's 12 dollars - 12 dollars?" "I stopped by on my way to work" "I wanted to try the lunchbox you make" "You're busy from early in the morning" "What should I get?" "Aren't you leaving?" "Oh yeah." "I am" "Do you go ice climbing?" "I heard that is great" "Heard the snaps on this thing is terrific" "I don't do ice climbing but the customers have complimented on it" "Excuse me, please look around" "I..." "I don't think we should see each other anymore" "I came here to tell you that" "I'm not saying we need to do anything right now" "We have our own situations, so let's take it slow" "Did you forget everything I've done for you?" "Watch me" "Watch what I will do" "You're late" "It's okay." "No one's watching us" "You were charged more this month for the water" "What?" "I hear some leaking sound at night I was wondering if you knew" "You want me to fix it?" "No, it's fine" "Alright then" "See you later" "By the way" "Your clothes seem gaudy today And your make-up is heavy" "Detective Jo!" "What are you doing out in the cold?" " I brought some hot..." " Left the bicycle" "Left the bicycle with flat tires here" "Bicycles?" "Meticulously destroyed the victim's face and fingerprints but left the victim's things on the scene" "You're saying the killer left the bicycle on purpose?" "What if he did?" "And tell us the time of the murder?" "Why would he do that?" "To prove Baek's alibi" "What?" "In order to prove Baek was in the theaters when Kim Cheol-min arrived here" "That's why the tires are flat" "So no one can ride it" "Then the window of time for murder is spread out and Baek's alibi becomes insufficient" "You still think Baek killed him?" "What if" ""Baek was at home in between 6 and 6:30"" "And Kim Cheol-min was killed there" "No way" "How can she move the body from her house to here in 30 minutes?" "She even has no car Did she grab a taxi?" "Also, she had to rent the bicycle She can't do all that by herself" "It's impossible, right?" "No way Especially, a woman by herself can't" "The victim's clothes we found here What was the size?" "What about it?" "That's not important." "I found another suspect" "What?" "Did Ms. Baek ask you to kill Kim Cheol-min?" "Hwa-sun could never kill someone or hire a hit man" "And do you think I'm stupid?" "Even if I like the girl you think I'd kill someone?" "Then you killed Kim Cheol-min without her knowing?" "Because in order to be with her, Kim Cheol-min had to disappear" "What?" "What did you do on November 9th?" "Look here guys" "When will you stop bothering Hwa-sun?" "Well..." "Until we have no reason to" "November 9th" "He's not our guy" "Geez man" "He has a clear motive A motive!" "So the motive" "The reason" "What?" "There is someone but..." "Yeah?" "Who?" "But there is no motive" "Write question #1 on the board and if you have the time, do it up to #4" "Hey" "So you are the disciple of Doped-Goras" "Excuse me?" "Back in school, your teacher's nickname was Doped out Pythagoras" "Aren't his problems difficult?" "Everybody says it's hard but I like it" "Oh yeah?" "Why?" "Well..." "His problems have blind spots that mislead people" "It might seem like a geometry problem But it's actually a function" "You're killing them all" "Go on" "Yes, sir" "Study hard" "Let's go to the break room" "Okay" "What's up?" "Obviously, you're not here to check out my tests" "Don't take this personally" "According to this, you skipped the morning class on November 10th" "And you came to work in the afternoon What happened to you?" "A cold" "Really?" "What do you mean?" "And you were absent on the 9th" "I heard that you sometimes skip morning classes to do your math research" "But the administrator was surprised that you were absent on the 9th and 10th" "Said you never took off for two days in a row" "I haven't?" "Is that weird?" "A scrupulous person like you" "It's odd you didn't come to work for a mere cold" "On top of that, you were absent the day before" "Did you go see a doctor?" "What do you want from me?" "I suddenly want to ask you this" "Making a problem no one can solve or solving that problem" "Which is harder?" "Did you pity Baek Hwa-sun?" "She killed a person" "I have to go" "See you later" "Auntie" "The next door." "He is here" "What're you doing at my place?" "You're home" "I'm almost done" "Isn't Kim Cheol-min about 5ft 6in?" "Don't they seem too big?" "These fit you" "Don't they seem too big for 5ft 6in guy?" "Guess so But you can wear pants however you want" "I felt uneasy so I thought well and hard" "But this has to be an unmotivated murder" "That's why there's no suspect" "You think a psychopath did it?" "Usually, when a murder happens the killer will do anything to hide the body" "Bury in the mountains or sink it in a reservoir" "Even if he didn't have a car" "Han-river was right in front of you" "If I were him, I'll tie the body with something heavy and sink it under water" "So you're saying the killer left the body on purpose for others to find" "Yeah, he's a psychopath He wants the world to know what he did" "At least that's my guess" "Then think about it this way" "The killer wanted the body to be found" "That's right" "Then this actually makes sense" "Nov. 9th Absent Nov. 10th Absent" "His problems have blind spots that mislead people" "It might seem like a geometry problem But it's actually a function" "Right?" "JINSUNG Inn" "There was an empty noodle bowl and he was gone" "So you didn't see him the day before his murder either?" "Chinese food... think it was around midnight He asked about food delivery" "I gave him the number for a chicken delivery" "Over the phone?" "So you've never really seen the guy's face." "Have you?" "Mister" "Mister" "No, no wait!" "Mister!" "Wait" "Mister!" "Hey!" "You going up?" "Stop right there!" "Hey!" "Until now" "I only focused on Baek's alibi" "But the alibi wasn't important in this case" "The problem was the dead body" "Really?" "But I..." "I hope I'm wrong" "Looking at the homeless, you said they are precise like clockwork" "And you said when one gets free from clocks, one will become even more precise" "That's for people who are aware of time!" "For people living within the clock!" "I have no idea what you're talking about" "Did you kill someone?" "Even if you solve this problem, it won't make anyone happy" "Nor change anything" "You..." "You think it's going to change anything?" "Yoon-ah must be really gifted at math" "What brings you here?" "It's just that..." "I received these at the store today" "Stay away from Baek Hwa-sun" "You bastard can never make her happy" "Is there anyone you know who might do this?" "Should I call the police?" "No, no police" "You said you trusted me that I'll protect you no matter what" "Please let me in" "I have to ask you something" "Seok-go" "You like me, don't you?" "That's why you're helping me." "Isn't it?" "The past few days, you feel like a stranger to me" "You sent those pictures, didn't you?" "What?" "You don't want me?" "Isn't this what you want?" "I should've known there's nothing free in this world" "All men are the same It's so obvious" "Do whatever you want, do it" "Who cares if you're a pervert" "I brought this unto myself" "Why?" "Why are you doing this to me?" "I barely escaped from a lunatic" "How can I live feeling so suffocated?" "What is it you want from me?" "Go home" "Yoon-ah's waiting" "Do you love Baek Hwa-sun?" "Who?" "Who are you?" "How much do you love her?" "Can you die for her?" "Huh?" "What the..." "Who the hell are you?" "What the fuck?" "Asshole" "Who the hell are you?" "Come here fucking" " Asshole!" " You want to die?" "Who the hell are you?" "You're that fucker You sent those pictures, didn't you?" "You messed with the wrong person You crazy asshole" "Did you find it?" "He could be a real criminal Look closely" "Not over there, look up!" "If you don't break up with him I'm going to kill him myself" "I got it" "I saw him for the first time on November 9th" "Kim Cheol-min..." "that filthy piece of trash" "He was lurking in front of the apartment" "As soon as I saw him, I knew he was Hwa-sun's ex-husband" "How did you know right away?" "I know everything about Hwa-sun" "What kind of music she listens to" "What kind of things she likes to talk about" "Which TV series make her cry" "Since when?" "What the hell happened?" "Your friend is a total psychopath" "Just now, he was caught in the act, trying to kill Nam tae-woo" "He also confessed to the murder of Kim Cheol-min" "What?" "And we talk through the walls" "The walls?" "I can hear everything Hwa-sun says" "She knows that too So she talks to me through the wall" "She said to kill Kim Cheol-min" "She said she's miserable because of him" "So I did what she asked" "But how could she date another man?" "Bitch" "I should've killed her first" "I found this in your mailbox" "You received threatening calls at the same time every day." "Didn't you?" "We searched the call history from a payphone booth" "The guy next door, he is a total psycho" "He just confessed to the murder of Kim Cheol-min" "Stop there!" "Captain's going to be back soon" " Just give me ten minutes!" " Detective Jo!" "Wake up, bastard" "Get up and look at me" "Seok-go Stop with the acting" "You didn't kill Kim Cheol-min" "At first I thought..." "You took pity on Baek and she asked for help" "So you unwillingly helped her move the body" "But the Kim Seok-go I know He won't kill anyone for no reason" "Because he is rational and logical" "But I overlooked something" "That as long as the logic fits, you can be the most brutal person" "That day, I saw the way you looked at Baek" "Oh, this bastard is in love" "Then, when Kim Seok-go falls in love, what would he do?" "When his loved one is in danger" "He will plan something." "Right?" "A flawless and perfect plan!" "That's interesting but..." "A hypothesis needs a proof in order to become true" "Fucker!" "Are you going to ruin your life for that woman?" "I just confessed to the murder of Kim Cheol-min" "Even if you solve everything, my trial would've been over by then" "If I get convicted in the first ruling and I don't appeal, then Kim Cheol-min case is over" "No, no. this is wrong You're out of your mind" "This is not love This is not real" "How can you waste your genius brain?" "It's not about my brain" "It's my heart" "Bastard..." "Bastard You shouldn't have let me catch you" "Bastard" "Let me ask just one favor" "Ms. Baek" "I don't know where to begin" "I don't know what's happening right now" "But I came here to confess the things I've been hiding" "Seok-go wanted me to give this to you" "I don't know what's in the letter" "But it's probably not what I'm about to tell you" "It makes sense you don't know anything" "Because you've been doing what Seok-go's been telling you" "It's only natural that you passed the polygraph" "You never lied" "On Nov. 9th, you actually did dine out and see a movie with your niece" "But you probably wondered why people only kept asking about Nov. 9th because you killed Kim Cheol-min, on the 8th of November" "Yes, Seok-go isn't innocent He's guilty of a crime" "Mang-won district riverside murder" "Kim Seok-go is the killer" "He really did kill someone" "That day, the first day of murder on November 8th" "Seok-go probably contemplated over the dead body" "If the police finds the body, they will find the real killer" "Even if the body is never found he thought you would live your life in agony, worrying when the body will turn up" "So Seok-go decided to commit another murder" "His plan was to trick us into believing the body was Kim Cheol-min's" "Just in case, no matter what happens he couldn't back out" "He perfectly blocked off his own exit to make it impossible to undo" "Hello" "Inn" "Seok-go made someone you don't know into Kim Cheol-min" "And kills him in the same way" "So the body we found wasn't the real Kim Cheol-min" "And then some place where no one knows" "Seok-go probably hid Kim's body so that it can never be found" "But you see" "The person Seok-go wanted to deceive perfectly was you, Ms. Baek" "That's why Seok-go stalked you" "But then, an unexpected variable me, popped up" "Protecting someone until the end" "Even taking the blame for someone else's murder" "Is this possible for a normal person?" "I'm not sure" "Are you his family?" "Are you his wife?" "You're not even his girlfriend" "From the beginning, he planned to take the blames for you" "So now" "Everything is up to you" "I just don't want that stupid bastard... to be miserable" "This is my heartfelt honesty" "And it is the truth" "I want to thank you for everything" "Because of you, I was able to keep going with my life" "I don't know" "Auntie, what are you doing?" "Huh?" "Hand me that" "Wow, you put everything in order" "May I bring in the ones outside?" "No" "Until you showed up in my life" "I only thought about dying" "I believed math was the only perfect thing in life" "So when I couldn't find the answers anymore, the joy became agony and despair" "Maybe it was the loneliness" " Hi" " Hi" "We just moved in next door" "Here" "My aunt made it I can't guarantee the taste" "Is there maybe something I can help?" "Pardon?" "It's nothing, bye" "That guy is a bit..." "But you can't guarantee the taste?" "I'm joking" "You know what's in those rice balls?" "That's when I realized" "There's something essentially as beautiful as the beauty of math in this world" "Hello" "Hello" "Miss" "Those rice balls were good" "That's great" "If you want, you can eat it every day" "You really came" "Hello, sir!" "I'm late" "Hwa-sun and Yoon-ah" "Thank you so much" "Mr. Nam seems sincere and trustworthy" "I hope he makes you happy" "Please forget everything about me and what had happened Don't ever feel sorry for me" "If you are not happy, all my effort becomes meaningless" "If you ever turn yourself in because of guilty conscience" "There's no longer a reason for me to live" "This is my last request" "I'll always pray for your happiness" "Always, Kim Seok-go" "Seok-go" "Wait" "Seok-go, wait Just need a word" " What is it?" " Please Seok-go" " Stop the bus" " Isn't that Baek Hwa-sun?" "Can you see me?" "Can you hear me?" "I'm sorry, Seok-go" "Sorry I said I feel suffocated" "I shouldn't have said that" "Seok-go, I..." "Seok-go!" "Why did you do all this for me?" "You can't just go away like this" "Seok-go" " Let's get going" " Seok-go" "Seok-go, Seok-go!" "Ms. Baek!" " Seok-go!" " Ms. Baek!" "What will happen to him?" "This is all because of me" "You're the sole reason I'm still here" "I'm so sorry"
