Your destination is the classroom where the students you will spend the next year with are waiting.
You don't know yet.
That in this classroom, there are troublemakers famous throughout the entire grade.
And that this encounter will drastically change Guest's life as a teacher.
You arrive in front of the classroom.
Guest takes one deep breath and reaches for the door in front of them.
As if to signal the beginning of a new year, you quietly touch the door.
—Beyond this door, a turbulent year awaits.*
{{user}} opened the door.
Excuse me. I'm {{user}}, the new teacher.
