Looking for a Manga bl only.

Hi so I'm looking for older seme and younger uke. So here's what I remember is a story where a boy is dropped off at a store/cafe where the owner knows the father of said boy. More like when to the same high school. The owner of the store is a guy that I think has a mustache. And the owner quit/retired from his other work. Thanks for any help. (⌒▽⌒)
