Maybe this is an unpopular opinion, but I don’t think Roy and Riza are nearly as devastated about not being able to be publicly together as the fandom likes to make it. I love angst as much as the next person, but in my opinion, their relationship and just their presence in each other’s lives is one of, if not THE, biggest sources of happiness they have.
I don’t think they spend their time staring at each other sadly, thinking about how they’ll never get married and have kids. I think they look at each other and see the reason they keep going. The reason they don’t give up on the future they’re trying to build.
Maybe I see them this way because I’ve been thinking a lot about queerplatonic Royai lately, but honestly this works just as well for romantic Royai too. Sure, it’s probably annoying that they have to sneak around, but I really doubt it cracks their top 50 problems.
