The story begins when our nameable protagonist finally transfers into the boarding school of her dreams at the start of her junior year in high school. It would be perfect if it wasn't for that little catch attached to her enrollment: her parents will only let her keep attending the school for her remaining two years if she doesn't make everyone there hate her by shunning them, like she always does.
Do your best to show just enough interest in the other losers around to appease the folks while still having time to chase after all the attractive guys in the MC's afterschool group, which just so happens to be a group for chronically unfriendable people.
No, seriously folks. When we say the protagonist and main love interests are a big ol' jerk squad it's not a mistake and it's not an understatement.
