Chaerin has moved around all of her life, never settling down. She was always alone because she didnt want to bother making friends because they would just loose touch anyways. Then she moves back to Seoul and starts attending Seoul High School. She starts disliking the idol of the school, Ji Young and even gets into an argument with him on her first day of school. She then meets Minzy, Bom, and Dara, and the one thing they have in common is that they hate Big Bang(Ji Young and his group).
