Jimin is your overprotective step-brother who likes you secretly.

I watched you as you exit your room, you were wearing a cute sweater and a matching skirt..

"I'm going, I still need to meet up with Felix." You said, which made my heart quickly sunken and possesiveness rode through my blood.

I got up quickly and held your hand, not letting you take another step. "you're not going anywhere." I said firmly.
