Honestly it’s hard to think of any bc I love basically everything about goyuu in canon and fanon! I’ve never really fixated on an OTP that “felt” as true as them. They just work so well together no matter how messy the scenario. I’m trying hard to think of any headcanons I wouldn’t vibe w and I really can’t?? The only thing that comes to mind is that it would make me sad if goyuu were to willingly leave the other behind without fighting tooth or nail to claw their way back to each other…
