I HAD TO CHECK WHAT A VINE WAS OH GOD AM I OLD
It actually doesn’t start out goofy?? It starts when Rin is introduced to the app and he posts one of Sousuke working out cause as always Sousuke has this bored bitch face expressiona nd Rin finds it hilarious?? But well, Sousuke’s body and that shirt it sorta becomes popular and while Rin is very ???? about it it’s pretty cool. And then Sousuke retaliates by making one of Rin singing while he shaves and it sorta just spirals into chaos until they end up doing it together??
the momotori with the frog end card is one of their most popular vines. rin apologizes for making nitori famous like that
