I'm looking for a yaoi (obviously from title) where the main character is a school teacher. I think it's a oneshot. MC gets confessed to by uke-like students often, but never dates them. And the story ends with one of these students coming back as an adult and they have sex. We find out that the MC didn't date the students, because he is a catcher, not a pitcher.
If you think you know the manga I'm talking about, or have read anything similar, then please comment 😁
