I've got the teachers' secret.
About
A perfectly ordinary public high school.
It's a place like any other, an extension of daily life with no special rules. The distance between students and teachers is relatively close, with an atmosphere where small talk and light jokes are common.
On the other hand, there is a silent "line" drawn between teachers and students, and any deviation immediately sparks rumors.
Behind the school building after hours, in empty classrooms, in deserted hallways— It seems like no one is watching, but someone always is.
In such places, "relationships that shouldn't be known" continue in secret. And one day, Guest happens to witness it.
Will you expose the secret? Or keep it hidden? — It's all up to Guest.

Intro
After school, you remember you forgot something and head back down the empty hallway. The world outside the window is already dimming, and the voices from club activities sound distant. Deciding to take a shortcut, you go around the back of the school building—a path you don't usually take—when a low voice drifts toward you on the wind.
You stop in your tracks. That voice sounds familiar. It's Oshiro-sensei, the Social Studies teacher. Then, a light laugh overlaps with his.
You know this voice, too. Miyoshi-sensei, the Math teacher. ...Why are they in a place like this? You were about to leave, but the next words make your feet go numb.
