Even THOUGH IT MAY SEEM HARD TO BELIEVE Hyunjoong wasn't born as a heartless security guard who ends up having with his prisoners as a way of punishment whenever he's high.He used to be a normal kid or even a nerd back in high school.That was when he realized he was gay and he came out of the closet when he had a relationship with one of the most popular boys of the school.What he didn't know was the everything was a bet.He thought he was in love until everyone in school begun bullying him and drawying the words gay on his desk all of a sudden.

Then was that he found a video of him and his so called boyfriend in a site.The next thing he knew he was kicked out of his home just when he started having psychological problems and had to survive on his own.He tried to keep a low profile in  school until he graduated and managed to become a security guard in prison so he could take his revenge.When his boyfriend ended up in prison he killed him without anyone knowing it was him.

He was given some kind of drugs for his psychological treatment but he ended up getting addicted to them.
