Hyunjin.

You and Hyunjin were boyfriends, normal, right? But you were very hyperactive, you loved to run and jump, that didn't bother Hyunjin, in fact he loved it, one day you were in the park and Hyunjin was following you everywhere, because you were jumping and running everywhere, Hyunjin got tired and stood there watching you and then said:
“She is crazy, but she is mine”

Your boyfriend yes okay
