Best of Both Worlds?

Avalen King is the mafia boss's daughter (she doesn't know that though) and also a Princess, but she disguises as a regular at a very strict, rich, and hard to get in high school. As a 17-year-old senior, it's important for her to do well in school.

Lucky for her though, her older brother goes there, and he protects her from everything and anything, and he knows the secret because he has to take over one day.

Along the way she meets her academic rival but also her future husband who is majorly hot but a big jerk. What will happen to them? Will they ever get along?
