Could you imagine a world where all around the world there exists a school in each country where the students learn about different things. Those students don't just learn about normal stuff but also learn about acting. In each of these schools they have a leader. Not like a principle, more like a student that has more power than others. In the school there exists something they call a "reputation ladder". That reputation ladder is very important. If you are at the bottom you immediately become a social outcast or something else they call a "peasant".
In the school some people would fight each other just to get up the ladder.
If you ask why the principal or the teachers aren't doing anything about this, then there is a reason for that. They don't have the power to do that. If they did they would immediately get fired and not be able to get a job after that. They know that. That's why they're not doing anything about it.
But in the school there are two people that are the best of the best. No one dares to stop them since all of them are at a lower stage of the ladder. But sooner or later something interesting will happen to Lucas and Mia.
