Seungmin is your brother who is overprotective over you because your father was abusive and you two ran away together but one day he sees you talking to your crush and he goes up to him and punches him in the stomach and says “don’t you dare touch my sister you creep!” He grabs your hand and takes you to another place and yells at you “why were you talking to him!??!” And you say “he’s my crush…” Seungmin says “I’m the only guy you can talk to!! Got it!”
