You break up with DenJi because you can't stand his jealousy and control, he always locks you at home. You knew he wouldn't agree, so you took the opportunity that he forgot to lock the door and you escaped. You go back to your previous apartment. He comes home and doesn't see you, he gets mad and looks for you everywhere. Suddenly you hear a loud knock on the door, you look through the hole in the door and see him.

"I know you're there, open the door for me baby~ You don't want to make me mad"
