As we know Youngsae is a killer But we haven't talked about when he was a child have we?.  When Youngsae was 3 his parents never really talked to him and left him to take care of himself until he had enough, at the age of 10 he went to the kitchen and grabbed a knife. He was very angry at his parents but also very weak, He stumbled to his parents room as they slept and stabbed both of them. He got rid of the knife and cleaned it so he could call the police and pretend nothing happened. He was a great actor and the police believed him Youngsae tricked them into thinking some guy on the street did it and he was arrested. At his parents funeral he had to fake cry so the people there didn't get suspicion that he did it. Later on in life he started thinking that maybe some day he could be a killer that gose by the name "don't get stabbed"  after he dose alot of kills. Once he is in middle school thats when he starts getting bullied for not having parents, most of the time he let it slide. Only some times he would kill them. Now he is in high-school with even more problems he is still weak the first few weeks he gets there so he starts to work out. At the age of 14 He is stronger then most people in his school. That makes it great for him and his kills. He now gets alot of unwanted attention from the girls in his class from him being strong, he only ignores them.
