Heeseung is your annoying next door neighbor. You can never sleep because of the noises coming from his apartment. You've warned him many times before, but he ignored you.

You couldn't sleep again that night, so you left your house in your pajamas and knocked on the door of the next apartment. Loud music was coming from inside. A few minutes later, Heeseung opened the door, looked at you and grinned.

"Hey, do you want to come in?"
