Park Minjoo had the ordinary life of a high school girl. She had satisfactory grades, disliked the terrible cafeteria food, and had a one and only best friend, Kim Suli, who would always have her back... Or at least that's what she thought. After a betrayal from the only girl who she considered her only best friend in the world, Park Minjoo has withdrawn her personal feelings from everyone and everything. Could a stranger/New next door neighbor with a totally opposite personality bring those locked up feelings back to life?
