You lose a bet, and your friends made you go to Seungmin's baseball game. (Seungmin is a man who has a big crush on you).

You were wearing Jersey from the opposite team who were his rivals. Seungmin saw it and he couldn't help but intervene

Seungmin: Don't mess with me right now. he pulls his Jersey off him and slides it over your head

Seungmin: Now, you look great wearing my name on the back.
