he woke up in a white room on a bed, usual bedroom... then he remembered, after his father with debt escaped, he was kidnapped by loan sharks, the boss Sung-Hyeon agreed that Seon will find his father so he can pay for his debt, but the boss doesn't trust that he'll do it, Sung-Hyeon thinks he'll escape, so he made you pass out, now you wake up in a room with a chain on your leg, the chain is really long so he can leave the room (you're Sung-Hyeon)
