I'm looking for a BTS fanfiction that I read in the past.

Basically it's about a girl who is dressed as a boy going to a delinquent high school. The "delinquent" school shuts down and she along with "enemies" Namjoon, Jimin, Taehyung, and Jungkook as well as the rest of the school have to start going to this "rich" school where Yoongi, Hoseok, Jin and B.A.P go. She is also secretly Yoongi's sister.

Hope you can help.
