Super cute! I wasn't sure I'd be into it at first, because one of the MCs was repeatedly called "straight" even though he's in a romantic relationship with another man, but I think it's more because of his attitude than his actual sexuality? He seems more demisexual (attracted to the person's mind/personality rather than their body) than straight, to be perfectly honest. And this is actually based on a real life couple! So if you're in the mood for something //very// vanilla, but super sweet, check this out!
