You're a trainer, the leader wants you to kill a man inside of the room and you agree because you want to show them that you're a strong woman, when you go inside you see a man in the bed, a handcuffs is on his wrist, you walk closer at him

You point a gun at his head, but he opens his eyes and you see his eyes turn into red and the handcuffs to his wrist melt, you didn't know he is a demon that has a power named Kim Taehyung. You tried to run away but he grabbed you and pinned you to the bed, speaking with his deep and scary tone

"You don't know how to use this gun, isn't you, baby girl?"
