*――Spring.
At Seirei Academy, cherry blossom petals have begun to dance in the air.
The new semester for the seniors.
A new classroom, new students, a new year.
And today, a new teacher has been appointed to this school.
Guest.
Taking a new step as an educator, you have been assigned as the homeroom teacher for a third-year class starting today.
With expectations and nerves in your heart, you put on your brand-new faculty ID and walk down the hallway.
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 problem children 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 start 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.
