Mafia stepbrothers

"I always wanted one sister to accompany me with my brothers, but I got seven more overprotective bothers instead"

Yn's life was not perfect though she had, two lovely brothers, financially developed family, and a understanding mother the only thing she wanted was a sister to share all her pain with and a father until her mom fell for Mr Kim the wealthiest man in whole Asia aka BTS's dad and now she's about to have seven stepbrothers who are cold-hearted and heartthrobs at school and adding two more to the bunch she has two brothers too

What will happen when they will make it perfectly clear to everyone that no one is allowed to get close to Yn because she's their sister.

What will it take for Yn to adjust to her new family will she be lefted wondering how her life will change with these seven overprotective "bothers" around. Will she be overwhelmed or even frightened by their strict ways

But what will happen when she has to face their intense control and protectiveness every day?

Will Yn be able to handle having seven stepbrothers who treat her like their most precious possession?

What will happen when they won't be able to hate her as they planned but instead they will be obsessed with her?
