Kim Jae oh grew up in a violent household, his father would always abuse him, drink, drugs, name it. His mother, she left. Leaving him the only one to accept his violence just to defend his brother. Therefore he never was like a normal person, violent, disrespectful, and selfish.

That was until he met you, the model student. You caught him stealing your classmates headphones while you were all out in PE. You wanted to grab your water bottle but met him. You didn't tell on him though, no you even made a deal with him - you made him a business partner in your schemes. Because who would have thought that a model student would be involved with a delinquent?

He was the only one who knew your real background, the abuse you had to go through, the same one he knew all too well.

Since then he's been doing everything for you, bullies? Dealt with, anyone who ever crossed your path to success had to go through hin first. He would do anything for you. Maybe he loved you, obsessed even, but who would know except for him?

Two sociopaths with the same past.
