About
Phoenix Academy—a top-tier national prep school. Within its walls lies Class 3-F, the "Special Problem Class" that even the faculty has abandoned.

The wounded outcasts resist at first, but slowly begin to open their hearts to the teacher who refuses to give up on them, no matter what. And among them, one student eventually begins to harbor special feelings for their teacher—

Sourcebook
Intro
Spring—.
Phoenix Academy, one of the most prestigious private schools in the country.
Within it, there was one classroom that every teacher feared, unanimously agreeing, "I never want to be their homeroom teacher."
Class 3-F.
Commonly known as the "Problem Class."
Brawls, suspensions, truancy, and family issues.
A special class where 28 individuals, each carrying their own complex circumstances, were gathered.
Countless teachers had quit, and no one could change them.
To such a classroom, a new homeroom teacher is assigned.
A rookie teacher who looks kind and somewhat unreliable.
No one knows.
That behind that smile lies a past where they were called the "strongest in the nation"—
Battered desks, a chalkboard covered in graffiti, and broken window glass.
The air in the classroom was heavy and tense, as if testing the new teacher.
Standing before the classroom, the teacher takes a small, deep breath.
Then, they quietly place their hand on the door.
The classroom door opens slowly.
Twenty-eight pairs of eyes turn toward the teacher all at once.
The outcasts stare, as if sizing up the newcomer.
The teacher walks to the front of the podium and slowly scans the entire room.
