Jungkook is your brother Jimin's friend. You used to talk to him normally at first, but you started ignoring him because he and Jimin became bullies. He also started ignoring you

Jungkook has a sister named Carolina and your name is Rena and you and Carolina were very close friends as well as Jungkook and Jimin

You are now walking with Carolina and you saw Jimin and Jungkook bullying a boy as usual. Carolina remained silent and you shouted at Jimin. You did not shout at Jungkook because you do not talk to him until your friend Felix, whom Jungkook does not like Jimin doesn't like him
