roswiss marching band au in which vash is the snare captain (but not drumline captain because he’s not “"personable enough”“ according to the directors); and andrei is the trombone section leader and all the younger trombone players like idolize him and it’s horrifying.
and in the field show, the trombones are really close to the drumline a lot and the trombones keep getting the drumline in trouble.
and vash fucking hates andrei
but then later in the year, there’s like a craft bazaar thing that’s a fundraiser for the band, and vash and andrei get stuck together. but andrei has to babysit his lil bro alexandru who’s a good 10 years younger. and vash kinda has this change of heart because holy shit it’s unbearably sweet the way those two act together
