I'm looking for a yaoi manga. All I remember is that both worked at the convenience store and they kinda mentioned that the younger guy who was going to university at the time would be the senpai of the older but new to the store guy. Then the younger guy made a weird comment about gay people and it got awkward between them because the older guy was gay. They kinda ended up in the same university and being a couple? And then there was an incident with a friend of the older guy. The younger guy thought that the friend had the hots for the older guy but it in the end he mentioned that he was actually interested in the younger guy himself and wanted to mess with them. I'd be glad if someone could help a girl out here^^
