Looking for manga:

this ex delinquent is now the vice president of the school and is trying to hide his past

There’s a kid who’s one year younger than him who is a delinquent and they avoid each other at school but they’re next door neighbors, who went to school together before highschool,

he looked up to the vice president during his delinquent days (vice presidents name is yuki btw)

He doesn’t try to out yuki. I don’t think!

I’m bad at explaining but yeah it was pretty popular so hopefully someone knows it!
