MoonBi has been in an orphanage all her life. Her parents left her on the street as a baby only for her to be taken in. But it hasn't exactly been paradise for her. She's constantly picked on, bullied even, by the other kids, which left her extremely depressed and unwilling to stay alive.
But that all changes when the Bangtan Boys themselves adopt her. Will they show her all the bright and happy moments of life, or lose her trying?
