You Angel sent by God himself, it is
enjoy! (⌒▽⌒)
There are four sisters who are considered creepy, but they are nice people, just you know Addams family vibes. They where mainly home schooled, but youngest falls in love with a "pretty guy" so she decided to go to his high school to try and win him over. There she meets another boy and he decided to help her with her romance, but he is also falling in love with her.
The pretty boy, also has three brothers and they are considered "perfect" so the guy has a complex.
