Manga Hunt

im looking for stuff like shimanami tasogare, ao no flag, until i meet my husband and those bunch
doesnt have to exclusively be bl anything's fine

So i remembered this obscure bl manga i read a couple years ago, and I can't find it.

I know that the two characters met in a convenience store and fought over the last drink(or bread?) And one of them is russian and doesn't speak Japanese. I think at the end of the story the other character like says something in his language like thanks.

I don't think it was very long so it might have been a one-shot. Please help find this! Thxxx
