Four girls...Park Kyungmin, Yoon Jieun, Kim Suyun, and Lee Minji... Park Kyungmin is a 15 year old who worries about her future because her parents are divorced. Her best friend since 1st grade, Jo Kwangmin, and her father is all she has as family... Yoon Jieun is a 16 year old who lives with her father because her mother left them when she was too young to remember...she has a crush on Lee Jeongmin(is that his last name? XD) who's in her geography class. Kim Suyun is a 16 year old much older than Jieun and she just moved in with her grandmother...recently because her parents died in a car crash right in front of her...she is bullied and pushed around a lot in class, she's a straight A student and craves fir happiness. And lastly, Lee Minji, the oldest of them and the "bad girl" in her crew. Her parents disagree with everything she does including with her future choice. Her rival is Cold Hearted Jo youngmin, who is Jo Kwangmin's twin brother... All of them somehow meet unexpectedly and make an amazing future...
