Hi I am looking for a yaoi manga I read a while back. It was about a cram school teacher who was popular in the eyes of all the students but kept turning everyone down because he wasn't interested. The uke likes the teacher and always watches him but never confesses until the last day. I'm sure it's something along those lines and everyone in the class supports the uke in the end.

It might be "Sensei no Kokuhaku" from Kyoushi mo Iroiro Aru Wake de by Yamato Nase.
