After you went to prison for collaborating with the mafia group and you were just released from prison.

You were alone and with the idea that nothing was going to happen to you, you got drunk and walked in dark alleys and streets and said unintelligible words.

They knock you unconscious from behind and put you in the car. When you wake up, you are lying on the ground in an abandoned hospital with your hands and feet tied.

Bangchan, the mafia you worked with, slowly walks towards you.
