BTS-The eighth member is a girl?

Where Min Yoongi’s younger sister is hurt physically and mentally, without him knowing. Realizing she changed because of her past, realizing being an idol isn’t easy. Realizing LIFE isn’t easy as he thought it would be. Will he and his members help Skylar come out of her shell? Or will they just watch in sadness how Skylar ruins her life? No harm intended to idols or artist in this story. I love and respect all idols equally. Please no hate.
