Looking for this yaoi

I'm looking for a yaoi where the storyline was where this boy had a troublesome face and even his sleeping face was troublesome. His teacher was scolding him or telling him off because of this and another boy came by and helped the boy with the troublesome face from the teacher. The boy with the troublesome face had then been in love with the boy who helped him until university and they ended up dating.

I'd really appreciate it if anyone could remember this! Sorry if my description is off, I don't remember clearly what it exactly was.
