I know this story is pretty crappy but it was my first story ever, so please read my better version of this called Dauntless High it's way better and here's the summary.

Four and Tris have hated each other since the day they met. Which has been since they were babies. Their parents are coworkers and they're neighbors in their huge mansions. In a school of 10,000 students Four is the jock and quarterback who EVERY girl loves especially Nita who is OBSESSED with Four and all Four wants is to get away from her. Everyone loves Tris, even Lauren the most popular girl with an entourage of like 100 people. Tris and her group,  Shauna, Christina, Marlene, and Lynn fight against Fours group, Zeke Will Zane and Uriah.
