there's no earthly way they haven't been super casually all up in each other's space for a while now, because dina's his roommate and bandmate and sort of lifemate after they bonded over being ditched by their respective partners and ended up living together by beautiful accident. and calvin's his pseudo dad and personal idol and latest employer. his c/p blurb is here until i get off my butt and rewrite it into something that isn't so 'i wrote this in the bathroom at work' but it's a functional enough summary.
