Truth dare, spin bottles

As they approached the school, Billy and Tommy split up and headed to their respective classes. Billy made his way through the bustling hallways, the familiar sights and sounds of school welcoming him after summer break. He couldn't help but feel a sense of anticipation mixed with a touch of nervousness as he opened the door to his first class of the day: math. Taking his usual seat towards the back of the classroom, Billy looked around and noticed the familiar faces of his classmates.As the chatter died down and the teacher began taking roll, there was a sudden flurry of activity near the door, a girl with black hair and a purple diadem entered the classroom excusing herself, she took the seat next to Billy.

So, I'm trying to do a classic, school, with a 2000s aura and slight AU story, I'm not sure how this is going to evolve, this is my first time writing something, and English is not my first language, so please be nice:)I accept suggestions and constructive criticism btw.
