Any Deep Cut headcannons?
Romance HCs:
Frye's experienced in the dating world and dates around a lot. She mostly just enjoys getting to meet and know new people, though. Shiver, however, is pretty inexperienced and is crushing hard on Frye. She's pretty good at hiding it, but Frye's too perceptive to ignore it (actually, Big Man probably accidentally spilled the beans) As a result, Frye enjoys teasing her idol partner, egging her on to reveal her feelings. Frye's also mature enough to know a romance with your idol partner could become a major tabloid scandal if there was any drama, so she wants to make sure Shiver's feelings are true. Basically, she's waiting for Shiver to pop the question.
Also, Shiver has a secret punk-rock alter ego where she writes and screams angsty songs about killing and maiming your crush's boyfriends. Big Man helps with mixing and mastering. (That's where this art comes from.)
Ok so this was immediately de-canonized, like, a day after I posted.
Canon is (from a translated Splatoon magazine "interview"), their families were very close but the three didn't interact much as kids. The only became friends in middle school, when Shiver began hanging out with Frye because Frye seemed like a misfit loner. They began singing together, and would eventually recruit Big Man as their music producer.
