I saw the description of this manga a few days ago, but can't remember the name of the series/oneshot. It was about a girl who was confessed to (I think) by a student that was a bit rough. A teacher found them and told off the student, and in the process it was revealed that the teacher liked the girl that had been confessed to.

I'm not sure what the name was, and this is all I can remember of the summary. If you can help, I would appreciate it very much.

It sounds to me like Shounen Chuudoku. I like that story (though it's just a one-shot, with other one-shots in the volume). Hope this helps!

Yep, that's it. Thank you very much.
