Private Lessons with My Lover Teacher 2

Asakura Shinji can't sleep, so he wanders the town at night instead of lying awake in bed. Out on one of these walks he runs into his homeroom teacher, Hagino Umi, who scolds him for being out so late and then, unable to help him openly as his teacher, comes back another night in disguise as "Ogino Miu" instead.

That double identity is the whole hook: the same woman splitting herself between the teacher who can't be seen helping a student and the stranger who can. Their nighttime meetings turn into something gentler than either role allows during the day, and the story follows those stolen hours rather than anything happening at school in daylight.

There's nothing to steer here. It's a kinetic novel with voiced dialogue, so you read Shinji's nights unfold in fixed order rather than choosing how they go. The 2D art carries the teacher/not-teacher routine scene by scene, and the full translation covers the game start to finish.
