WAIT I HAD SIMILAR STORY
But the teacher is a she and my friend is the man. It's chemistry teacher also. The teacher is a substitute teacher that just doing practical teaching at our school. We met at 16 and he married this teacher when we're 22. I don't remember how old is the female teacher but i got weirded out by it when they made a video edit about how they met each other at school as their first meeting when my friend is still a minor
The way I stumbled across this after I met a former classmate and found out she’s married to our old chemistry teacher lol
(Way way way after we graduated from high school. They ran into each other 13 years after graduation… plus he was like 25 when we were 18). But how funny to see a manga with the same premise.
