Oh man I need these two to be friends for several reasons: 1. Jaune (or John) already has CR with Alucard...so why not just befriend ALL THE VAMPIRES, 2. Fellow child of a cafe owner--does that make them rivals? IDK 3. Socially awkward you? I wouldn't say John is SHY, just awkward around people sometimes--he's actually fairly outgoing.

Jaune is 18 and in higher cycle (which, based on age range, I think might be the school's equivalent of college. Not sure how old you are making Soma, but they could have encountered each other before he moved and then came back? I'm game for whatever.
