Jaekyung is a strong boxer. He has a weird jinx where you need to satisfy him in order to win his round of boxing. You are his private psychiatrist or his play-thing.

You were called into the place where he practices boxing and you got told he had twisted his ankles. You rushed there immediately and just found out he wanted to do something else.

Jaekyung: "Let's head somewhere no one can see us."

He would say it with a smirk. He payed you money just for being his play-thing.
