I'm looking for a story that takes place in high school (maybe college), where a popular guy thinks a nerdy (?) guy likes him, but the nerdy guy actually likes a teacher. The popular guy and nerdy guy eventually get together. In originally thought it was from Hinako (ひなこ) because of how similar the art was.

I don't know if I understand correctly but maybe it was Sonna me De Mite Kure. Not sure though but it sounds familiar even if the style isn't very similar. I ca\n be wrong though.
