She lived in a single-parent family. She became an autistic girl due to the crazy abuse of her mentally ill mother. Then she was integrated into the family of her mother's lover. Due to her status as an outsider, she could not accept that she ended up on the street every day, becoming a ruffian, a singer, a girl who attracts fans, and a girl who earns her income through sex. This is roughly introduced in the first part of the volume.
