BL in a store setting?

I've already asked in things but no luck there so I'm trying this. I'm trying to find a BL about a college student that one day goes to a convenience stores and the clerk catches his attention. The clerk is very pretty (according to others in the manhwa as well) and when the college student is leaving the store the clerk follows him outside because he forgot something in the store which he bought.

That's pretty much all I remember sadly... It's definetely not dangerous convenience store, but if you know any BLs that are set in a store, please drop them by!! They might just be what I'm looking for.

Thank you for your help (●'◡'●)ﾉ
