this game is vn that takes place in a school, a teacher discovers that a student named nippanpan is seeing someone and records it, because of that they start to relate
it has multiple endings and one of them they get married and have two kids. I remember that depending on the choices you get these endings.

An except is "A week ago, I received this important proof.
It is proof of the student's affection for another teacher at the school.
I've been recording the video for several days now, so it's solid enough.
I thought for a long time after that about what to do with it...
And today, I call her to meet me in the deserted warehouse behind the school"
