Are you my bias?

Park Seokmin is Jimin's younger sister. She hangs out with her Oppa and his friends all the time. Everything is going great, until she is asked who her bias in the group is. She can't answer the question because she doesn't know herself. All the boys like her and it is because of this that the boys make a bet to see if they can become her bias. Whoever gets her to say that their her bias gets to keep her with no fight from the other members. Will she be able to pick a bias? Or will she just be confused and lose those closest to her...

I'm sorry if the description is bad. Please read it anyways.
