"Our Seong Yeon High School has transcended Korea and joined the ranks of the world's best schools." "We have the best facilities and the best curriculum." "...A B and C. It's a very simple question." "What tangent means?" "A divided by B." "Most of the math classes are being taught in English." "Out of the 600 kids in a class, more than half of them go on to IVY League schools." "The rest go to universities in the country, but they go to the best schools in Seoul." "Because finals week is very close." "If you want to go to a college, then the tests are very important." "Because finals week is very close." "If you want to go to a college, then the tests are very important." "We have no time to worry about other stuff." "The student's food is prepared with care and has many healthy ingredients." "Fatty foods and fast foods are not allowed." "She must be crazy!" "What is she doing?" "!" "What is she doing?" "!" "What are you doing?" "!" "Turn the camera off!" "Turn it off!" "Episode 7" "ReporterGuYeonJoo ,the yougestSeoulCityPolice CaptaininUrinewspaper ." "Good morning." "Before Woo Hyun joined the Cyber Crime Investigation Squad 2007, she was a reporter." "I was trying to hack her laptop, but she had strong security on it." "She had vaccine programs going around the clock and she never touched any email attachments." "If she did date Woo Hyun, then putting security on her computer would be normal." "For now, there isn't any evidence that they were really dating." "That woman... knew the password to Woo Hyun's house." "But Team Leader Kim Woo Hyun didn't say anything about dating someone." "Are you getting jealous for a dead person right now?" "If Woo Hyun and that Reporter Gu Yeon Joo really dated, then she would be the first one to know that I'm not Woo Hyun." "And that woman is really close with the police station executives." "On top of that, when the Dae Young Team disappeared," "On top of that, when the Dae Young Team disappeared, all the evidence that we had was destroyed." "What's important to me right now, is that." "Now on this file... all I have to do is extract the other file that's hidden in it." "Like you said, Director, there must've been some kind of misunderstanding." "To be honest, I..." "It couldn't be... in here... 119... 119." "The phantom file that was in Shin Hyo Jeong's laptop..." "If I could just find out who the person that died was..." "When Director Nam Sang Won was here, did you notice if anyone else came with him?" "No, he didn't come here with anyone." "He came here by himself." "May I see the check-in list?" "Our resort only has VVIP coming in." "We only rent the units." "We don't have a check-in list." "But, why are you talking about something that happened a year ago?" "Is there some kind of problem?" "No." "The past CK Director and I were like father and son." "We gave each other information when either of us needed it." "But, early last year while I was on a business trip, he left a message for me." "I've been calling you but I haven't heard back." "I have important information." "I'm being watched right now." "If they know that I gave a tip-off, I will be in danger." "Please call me as soon as you can." "What's the important information he was talking to you about?" "Who knows." "I don't know." "When I got back from the business trip and heard the message, he had already died of a heart attack, at his villa." "Then," "Then, what do you mean when you said that Kim Woo Hyun has a secret in this case?" "I thought that the death was kind of strange, so I went to see his family." "But, do you know what I found there?" "[Inspector Kim Woo Hyun]" "So, Nam Sang Won and Kim Woo Hyun knew each other?" "Kim Woo Hyun said that he didn't know who Nam Sang Won was at all." "But..." "What is this?" "The day that Nam Sang Won died..." "It's a CCTV that was near the resort, and he's on it." "There isn't any evidence of Kim Woo Hyun and Nam Sang Won meeting that day." "But, Kim Woo Hyun definitely has something to do with the death of Nam Sang Won." "If you look into it, you'll probably be able to catch Kim Woo Hyun." "Do you still have CCTV captures from a year ago?" "No." "We only have them up to the last 6 months and then they're thrown away." "Ohh, you guys use Sa Sul Security." "Yes." "But, the angle that the CCTV's are at...." "Huh?" "It's kind of strange." "I guess you guys intentionally don't make captures of the doors to the houses." "Yeah, that's because the customers don't want it." "But instead, there are CCTV's here and there." "We protect the inside of the unit, but we do a strict watch outside of the unit." "So you're saying the security outside is tight, right?" "If you remember anything from then, please call me." "Yes, sure." "Please, it's a favor." "I understand." "Yes, it's Hae Myung Resort." "There's someone snooping around the Nam Sang Won case from a year ago." "Yes." "It's Team Leader Kwon Hyuk Joo, from the Cyber Team in the police station." "Oh alright." "If he comes again, please tell me." "Lieutenant Kim." "Here's the report from Safe Tech about the DDoS attack." "They made it really well." "They made it really well." "Has Safe Tech always been this good?" "From what I knew, they weren't all that great..." "But then all of a sudden, they got better." "The people that did this are Safe Tech?" "Yes." "Where are you going?" "I'm going out for a bit." "Bye." "Bye." "Yoo Kang Mi" " Seong Yeon High School case." " Hey, Tae Kyun." " Yes?" "What is this?" "The Sung Yeon High School case..." "The one Yoo Kang Mi went out to." " Ah, it seems that a student commited suicide." "Is that so?" "Wait a sec..." "If it's Sung Yeon High School..." "Sung Yeon High Case." "Ji Won." "Sung Yeon High School." "The student that died is this student?" "Yes." "His name is Seo Jin Won." "Sung Yeon High." "He was in his third year." "Since it was night, there wasn't anyone that saw him fall, but we think he fell from the roof." "On the roof, this student's ID card was there." "Why is his hand like this?" "From what his friends said, they said that he hurt his hand in art class." "Well, since we don't know if he was bullied or not, we're investigating that." "Something that was a bit strange, is that all the e-mail he got were deleted afterwards." "How about the deletion time?" "It was 10 minutes after the suicide." "Someone else cleaned it up." "You should go and check up on that yourself." "No!" "I'm sorry, but I know this rooftop very well, too." "Why did you do that?" "Even though a guy from our school died... the teachers are saying that the finals are soon, and they didn't even let us go to the funeral." "I didn't think that that was right." "I just wanted to show our thoughts as well." "Were you friends with Jin Won?" "We weren't that close." "We just volunteered together at places." "Jin Won, what kind of kid was he?" "By any chance.... was he ever bullied?" "Is that why he commited suicide?" "Jin Won didn't die because of stuff like that." "If he didn't die because of stuff like that, was there a different reason he did?" "I heard Jin Won got the Legendary Answer Sheet." "The Legendary Answer Sheet?" "The Legendary Answer Sheet?" "I'd love to get that!" "I hate midterms!" "Me too." "You always get first place!" "You don't need that." "Nu uhh..." "What is it?" "Get the teacher over here!" "The teacher!" "Someone call the police!" "Call the teacher!" "The teacher!" "Didn't you say that you graduated from our school?" "Do you know anything about the answer sheet?" "You know, right?" "The number one in their class just turned became a third year and" "I heard she commited suicide in the bathroom because of stress from the finals." "But, since then, whenever the finals started they said that her ghost appears." "That ghost picks one of the third years and puts in the answer sheet for the finals." "Whoever that gets the answer sheet turns into number 1 in the class, and it is said that they would commit suicide no matter what." "But, that's just a myth." "There's no such thing as the Legendary Answer Sheet." "No." "No." "No." "It's true!" "Jin Won said that he got that answer sheet." "What are you doing there?" "3rd Year Class 5, Park Ji Soo." "The mannequin prank, you did it, right?" "For now, go to the dormitory." "And after the test tomorrow, come to my office." "It's been a while." "Yoo Kang Mi, right?" "Yes, it has been a while." "That student wants to commemorate the dead." "It's frustrating." "In that time, she could memorize another English word." "I heard you became a police officer." "Aside from all of the other great colleges you could've chosen, you chose the police academy." "I'm on the case about the kid that died, Seo Jin Won." "Are you curious if he was bullied or something?" "Is it true?" "This is Sung Yeon High School." "There is no time for bullying or anything else." "It's just because the final exam is approaching." "For third years, GPA is their life." "Even just one little mistake could mess up all the hard work they put in the past three years." "There's no other choice but to be stressed out like that." "This is the original report of June 12th case." "By the way," "What do you want to know about this report?" "As I expected It's great even if I see it again." "Sefe-Tec invest a lots in the system and the facilities and people." "It's just the result of our investment. the" "I heard that you merged with Se Kang Securities, right?" "Money must be a good thing!" "The analysis of malignant code the patern of DDos attack, everything is explained clearly." "If it is written by the suspect who did the DDos attack, people will believe it." "Pardon?" "What is that..." "Can I accept it as your compliment?" "Please leave us alone for a while?" "The report is very impressive." "Although you had this good company," "Why didn't you use it when Se Kang had the DDos attack?" "How much the Save-Tec has the ability," "It can't be better than the Cyber Crime Squad." "Or," "From the first, did you already know there was no second attack?" "What do you mean?" "I heard, after DDos attack, Safe-Tec earned lots of practical profits." "The stock price went up and the rank in the industry also went up." "Isn't it a very profitable self-fabricated scenario?" "Just if I made a novel." "Should I write a novel too?" "Let's say someone really plots such a self-febricated scenario." "Then, the National Police Agency, the National Intelligence Service and the articles," "Everyone will pay attention to us." "I must say it could be a very dangerous self-febricated scenario." "So, the reason for such a dangerous self-febricated scenarion is only for increasing the stock price once?" "Before the accident," "Have we met often?" "Still it seems you can't remember it" "If you remember it, please call me." "You changed the password." "Do you want something to drink?" "By the way," "If people get hurt, does their taste also change?" "You never have the alcohol before." "I thought this way." "Since we met in the Director's room, when I saw you here before also," "You don't seem like" "Kim Woo Hyun Whom I knew before." "You said we were in relationship." "It's because you suddenly did this..." "I remember that I have an urgent matter." "I will call you." "I'm not the only one." "There are more sympathizers inside the Police." "The Police , the Prosecution and the Press." "All are connected to him." "Woo Hyun knew who killed Shin Hyo Jeong," "He was a sympathizer of that conspiracy." "If Woo Hyun was alive, the real suspect would try to contact Woo Hyun." "They're going to try to get in contact." "Oh, I just needed to take care of some work." "I need to check something." "By the way, do you thonk Lieutenant Yoo will be fine?" "I heard she had a bad experience when she was a student in Seong Youn High School." "What 's that?" "I heard that you met her there at that time." "Oh, yeah." "He can't have Alzheimer in that age." "What is that?" "Uri newspaper 2011, 09,12." "the Reporter Gu Youn Joo" "Uri newspaper 2010,11,30." "the Reporter Gu Youn Joo" "Investigating Subject Gu Youn Joo" "Investigating Subject Gu Youn Joo" "There is no matching result."

"I'm the Northern Police Cyber Investigation Team Leader Kim Woo Hyun." "You are the new Team Leader whom I heard of." "We had a tip-off that the suicided student had a bully." "But the cellphone had destroyed because it fell down with her." "Can you repair it?" "I will try." "Is there any other digital evidence?" "There are computers in the student's dorm." "Student." "Eun Sol..." "Eun Sool, I killed her." "I said I killed her!" "Eun Sol..." "What the Ilsan Police said is true." "Seo Jin Won." "All emails that have arrived within the past week are all erased." "But that's something we don't know about." "The roomate wasn't in this room during the time the emails were erased." "I will have to check the travel route of the attached files." "Legend's answers?" "What?" "In a deleted email, Seo JinWon downloaded a file named Legend's answers." "What do you mean by answers?" "What kind of kid's joke is that?" "Legend's answers.hwp" "2012 1st semester..." "Name:" "Cha SueYeon." "Lengend's Answers.hwp" "The students who recieved the Legend's Answers, they commited suicide." "JinWon just commited suicide because of his stress." "There is nothing like Lengend's Answers." "Teacher." "Again." "Oh my gosh, it's already the second time." "I know." "How did this happen!" "I heard a weird noise out here so I came out and..." "But the same place as JinWon...." "Where is this student's room?" "This girl student's room number is 504." "Recycle Bin" "There are no emails in the recycle bin." "Who's first?" "1st place:" "Kwon EunSeol. 2nd place:" "Yoo KangMi." "EunSeol made 1st." "Yoo Kang Mi...2nd place." "EunSeol is first place?" "KangMi, I rose my grade." "Tell me the truth." "Did you get the answers or not?" "I told you no." "If not, how did you get 1st place of the school?" "All of the sudden you rose grade, and you are all that." "Kids like you don't have the right to listen to the lectures." "Guys, if I don't get into class this time either then I'm in danger." "Please, please." "Can you let go for once?" "Girls, please, please." "KangMi." "KangMi." "KangMi, please open the door for me." "Kang Mi." "Kang Mi." "Kang Mi." "KangMi, please open the door for me." "Kang Mi, Girls!" "Please open the door." "Kang Mi." "Kang Mi." "Kang Mi!" "Kang Mi!" "Kang Mi!" "Kang Mi!" "Kang Mi!" "What are you doing, here?" "Our school costs 1000 won to get in." "For 3 years, 6000 won." "Best education, best curiculum." "It is made by the parents wishes." "That's why to live we study." "Give all that money and you can't just not be doing well in school." "EunSeol's house condition was not good." "They barely got the money to let her come to school." "They made debts for her to come here." "Because of us, at the end, she died." "At the end, EunSeol, chose to commit suicide." "That one time in our lives, we can lose, and that we can trip," "No one taught us that." "If we trip, we learned that, that's the end." "There wasn't such thing as the legendary answer sheet." "EunSeol just tried hard..." "There was no legendary answer sheet when Eu Sol died, but now there is." "Dead Seo Jin Won had the legendary answer sheet." "Not Cha SueHyun who died second." "I checked Cha Soo Youn's computer, her mail which she had received within a week has deleted like Seo Jin Won's." "But, there was no legendary answer sheet file." "Then are you saying the kids dying has nothing to do with the answer sheets?" "No." "Then are you saying the kids dying has nothing to do with the answer sheets?" "No." "It is definately related." "When you delete a mail, you don't need to use the person's computer." "If you know the ID and password, you can delete it in a different computer." "Why?" "Who is it?" "What's going on?" "Wake up a bit." "Hurry." "Teacher, hurry please." "Wake up!" "I said wake up!" "Oh my gosh, what to do?" "Is there anyone here?" "!" "JinWon!" "Seo JinWon's emails." "Recieved emails." "Do you want to delete it permanently?" "Yes" "In a different computer the person logged in and deleted it?" "But Cha SueYeon's email were deleted in Cha SueYeon's computer personally." "That's right." "Cha SueYeon could've deleted the email in a different computer or cellphone but why did the person made Cha SueYeon delete the email in his computer?" "Legend's answers." "The person did not come to delete the email but she came to delete the real file." "The real secret that someone wanted to hide.." "It's the Lengend's answers file." "However, why did Cha SueYeon delete the file personally but" "Seo JinWon delete the email in a different computer?" "In Cha SueYeon's room, you said that you saw the girl student right?" "Yes." "Seo JinWon, is a boy student." "Do you think a girl student would be able to secretly go into a boy's room that easily?" "She couldn't do anything but delete the emails." "Then, if we find that girl student, every secret would be solved." "I requested the IP address to the communication company, which was used for deleting Seo Jin Won's email." "Detective Lee Tae Gyun will find out and call me soon Then, we will know who delete the email." "Did you request it to the communication company?" "It's not hacking?" "Well, I thought some other stupid things would happen again." "Is your arm okay?" "No. 1 Cyber Crime Squad of the National Police Agency, Team Leader Kwon Hyuk Joo?" "Yes." "He is investigating the Nam Sang Won Case." "Alright." "I will call again." "Did some problem come up?" "Uncle, this is not a problem that you need to concern about." "Do you have some artworks that you like?" "It's not like if I have somethings I like, I can keep it all." "I am always cautious." "You are not the successer of the Se Kang group." "I know." "If you know, why do you keep making problems become bigger?" "You mean the merge with Sefe-Tec." "I did it for only Se Kang group." "These days, the internet security is more important than the door of safe." "We can't depend on the outside company with this important thing anymore." "And the Safe-Tec vaccine program has been proved in this 6.12 DDos attack." "I think it will be a big help for the Se Kang group internet security." "and also this time, we should check the internet security of the Head Quarter." "Okay." "I will discuss it when I have a CEO meeting of the affiliates." "Thank you." "Father." "I got a car ready outside." "Keep in mind of what I said." "I understand." "No matter what you do, you can't take my place." "If you don't want to be like your dead father," "I am saying for you to live calmly." "Alright?" "That's right." "I am not interested stealing your place." "As you know, the vaccine program is important." "Of course." "The vaccine program is success, then everything ends." "Please find about Kwon Hyuk Joo who is the Team Leader of the Cyber Crime Squad." "Got it." "There is no CCTV at all here..." "Team leader." "Oh, did you get it?" "Yes." "Young Jae Security Chief Ahn said hello to you." "What the hello is!" "You are certain right?" "HaeMyung Resort." "Of course." "By the way, it was close." "Because they also keep this only for a year." "They almost destroy these." "Now, turn it on." "But are you sure?" "Does Kim Woo Hyun really related to this case?" "I will have to check from now on." "Now, May 16th." "Turn on the CCTV." "Yes." "Check the car number." "34DU4035 and 15DA5894 Both of them." "Yes." "Huh?" "It's the car number you were talking about." "34DU4035" "Is this man CEO Nam Sang Won?" "Right." "Now, turn backward more." "It's really Lieutenant kim Woo Hyun." "Now, we will go through the CCTV in details of this night." "Starting when?" "Starting now." "Starting now." "Start." "As you asked, I searched for the IP for the deleted email." "According to the telecommunication company, it was a smartphone." "Smart phone?" "Yes." "The number is 010010-070000700-0536." "The owner's name is Cha Soo Youn." "19 years old, a student of Seong Youn High School." "Wait a minute." "Can you tell me it again?" "What did you say the name is?" "Cha SueYeon." "Are you sure?" "Yes, that's right, Cha Soo Yeon." "Seo Jin Won, on his left hand he had a bandage." "Cha Soo Yeon, on her left hand she had a bandage." "Health Educator." "Yoon Hye Kyeong." "Hi." "I'm a police that's in charge of the Sung Yeon High case." "I have something I am curious about." "Student Seo JinWon, before dying his left hand was hurt, do you possibly know how he got hurt?" "In Art Class, I heard that while sculpting, by accident, he cut his hand." "Seo Jin Won!" "The Art Teacher was suprised so she brought him here." "It wasn't even time for sculpting, but with the knife, I guess he was fooling around." "Student Cha SueYeon's cellphone number?" "Yes, did you discover it?" "No, in the dormitory there were no cell phones." "We are trying to find it as well." "Yes, I understand." "Investigator Lee." "I have one more favor." "Please locate where Cha Soo Yeon's phone is." "Uhh, well tomorrow we have finals..." "I just need to know one thing." "Why was SueYeon's hand hurt?" "That..." "Tell me." "I will keep a secret between the teachers." "She cut it herself." "SueYeon, do you have this English Summary?" "Soo Yeon, I asked if you had any summarys..." "Soo Yeon." "I thought it was just stress." "Because of the finals coming up.." "I thought it was hard on her..." "Seo Jin Won, Cha Soo Yeon." "Before they died, both of them acted strange." "Did you know that?" "Be quiet." "They have final exams tomorrow." "Are the exams the problem right now?" "!" "2 kids died." "What exactly happened to them?" "How would I know?" "Jin Won and Soo Yeon, they were both getting very stressed out because their grades were dropping." "That's probably why they did that." "Because they have stress would they do the same things to their hands and die in the same place?" "This is not just an ordinary suicide." "There's definetly something to this!" "You know something, right?" "If I knew something, I would've probably already told the police!" "You take care of the kids that leave the dormitory, right?" "You take care of the kids that leave the dormitory, right?" "The 2 kids died around 8 outside the dormitory." "If they were to leave at that time, then they would have to tell you where they were going and why." "The art room." "Pardon?" "Before they died, both of them said that they were going to go to the art room." "They said that they left something in there." "According to the time, Director Nam got there 10 minutes earlier." "And Kim Woo Hyun arrived later." "It ends here." "There isn't a camera by the 12th." "Turn on another one." "Huh?" "You said that Director Nam died in number 12 (resort house number)." "Then, that would be the only place that we would have to look at." "Director Nam Sang Won did die in that one." "But there isn't any evidence of Kim Woo Hyun going there." "We need to find out if Kim Woo Hyun went to the 12th one or if he went to another one." "I see." "This car is Nam Sang Won's, but it is passing by the unit no.13." "Did you say he died in the unit no.12?" "Look for Kim Woo Hyun's car too." "Yes." "Here, here." "Stop, stop." "Now next one." "Yes." "It's passing by the unit no.14." "Good." "Forward it quickly." "Nam Sang Won's car is passing in front of the unit no.15." "KIm Woo Hyun also." "Well, next one." "It's not in front of the unit no.16." "Play the unit no.15 again." "Stop." "That night, Nam Sang Won and Kim Woo Hyun didn't go to the unit no.12." "It was the unit no.15." "Since we found Nam San Won in the unit no.12, we thought two of them met there." "Wait, what is this?" "32MEO5987?" "Yes." "Why?" "32MEO5987, a white sedan." "Do you know whose car is?" "Oh," "What is this?" "Why?" "Do you know the car?" "Hold on." "Why?" "Why?" "What's wrong?" "Case no. 2234." "32MEO5987" "It's Shin Hyo Jeong's car." "Shin Hyo Jeong's car?" "Nam Sang Won, Kim Woo Hyun, and Shin Hyo Jeong were all together." "we traced the location of the Cha Soo Youn"s cellphone which you asked for." "It was in Seong Youn High School." "I will tell you where it is." "Someone has a secret which is related to kids." "And the cellphone which has used for delete the secret  is in here." "Where would it be?" "Kids got the same legendary answer sheet." "They hurt their hand and came here before they died." "What would the reason be?" "From this cellphone, someone sent a mail to the kids." "The legendary answer sheet" "Have you heard that the teacher's computers were hacked a few days ago?" "I stealed the final answer sheet from the teacher's computers." "the attached file is the answer sheet." "You need the password for opening this file." "If you accept my request," "I will tell you the password." "But you shouldn't tell anyone about this." "If you want to start this game," "Keep your student ID in the rooftop till tomorrow lunchtime." "Keep your mid-term eaxm report card in the rooftop till tomorrow lunchtime." "If there is nothing in the rooftop," "Then I'll assume that you rejected my offer and give it to someone else." "Seo Jin Won's student ID, Cha Soo Youn' s report card." "After they died, all of these were found in the rooftop." "I got your item in the rooftop." "Now you do me a favor." "It is very simple." "Hold a knife with your right hand." "Stab your left hand palm with it." "There should be blood." "If you can bear it more, it will end soon." "Why did they come here?" "Kids... didn't fall from the rooftop." "Someone put wax on the pillar." "Although kids tried to hold the window frame with their left hand, since their hand got hurt, so the hand sliped." "the behavior which kids tried to get the password killed the kids." "This is... a homicide." "The pillar outside the window, the wounded left hand, the Items on the rooftop." "Everything is... planned."
