I'm looking for a manga where this plain looking dude finds out the prince from his high school is in his university. Long story short - prince is a sadistic seme and followed the plain dude there?

I remember a scene where it's like a teacher or something is mentioning that the school idol dude is going to the same school in a 'how lucky you'll know someone' way but the plain guy is put out as he wants to reinvent himself or something.

Help!

Akanai Tobira - chapter 4 > seriously, forget this one yearly too
