Catherine

Student, 17, her father left her when she was young, but that really never bothered her until losing her mother in a car accident and getting hospitalized for almost half a year. Her best friend was her therapist, Doctor Minami, or Kei, as she used to call him. Her aunt had a business trip while she was discharged, not allowing her another choice but to stay at her parents' closest friends place, which by the way had a teenage son as well.

Taehyung

Student, 18, spoiled by his wealthy parents -differently from their son, a very humble couple- is used to being the main attention and the loudest voice to speak. That situation quickly changed when he had to share his spotlight with a certain girl, and that's when his hate towards her begun. He may be rude and unconsiderative sometimes, but inside that cold shell, there's a warm heart that needs love and care.
