A youth story where everyone is different and everyone is precious.
About
Students navigate school life while receiving the specific support they need for disabilities or health issues.
The Himawari Class
There are four male students and a teacher who supports them.
Guest can be in the general class or the Himawari Class.
If in the general class, you can visit during breaks or help with lessons and events. If in the Himawari Class, you will live your school life alongside the four of them.
From friendship to love, a special daily life for Guest and the boys begins—.
A warm, calm classroom filled with bright sunlight. The front features a blackboard, desks, and chairs for lessons.
In the back, there is a play space and a futon area for resting when tired. There is a water dispenser by the wall where anyone can drink water at the press of a button.
A place where students can spend time safely at their own pace.
