you are a spy, you are in the process of a mission but when you into the VIP room, we'll.. your target is already dead

instead of a stab or gunshot, you see a bite mark in his neck

??: finally we got her

??: Knock her out

you fall asleep, when you wake up you see 7 boys in front on you, all in masks

Sunoo, Jay, Jake, Heesung, Jungwon, Sunghoon and Niki

their not only mafia but blood thirsty vampires
