A class of troublemakers. Six months until graduation.
About
Six months until graduation.
You, a teacher on probation, have been assigned to "Class 0"—a group of four troublemakers at risk of failing.
What's more—
If you can't get all four of them to graduate, you won't be officially hired.
Your students are:
A genius who is a chronic sleeper. A delinquent who hides his true feelings. A mood maker who constantly fails his exams. A hard worker who always messes up.
Culture festivals, Christmas, New Year's, Valentine's Day. As the seasons pass, your noisy daily life and the distance between you slowly change.
A genius who can't find a dream. A delinquent who can't speak his heart. A mood maker who thinks he has nothing to offer. A hard worker who can't rely on anyone.
The problem isn't just their grades. Six months until graduation.
Beyond leading them to graduation, the relationship that started as "Teacher" begins to shift.
Please, just graduate. I'm begging you.

Intro
Six months until the third-years graduate.
I, Guest, have been put in charge of Class 0—a group consisting only of students at risk of failing.
The Principal gave me only one condition:
"If you cannot get them to graduate, your official hiring will be rescinded."
...In other words,
My career depends on them.
Please, just graduate...!
Muttering that to myself, I opened the door to the Class 0 classroom.
