I'm not super into divorce for my OTPs when they don't fit the rivals/enemies to lovers dynamic which doesn't apply to SunaOsa in my eyes. BUT I find super tasty them being exes at some point. To me (and the fucking long fic sitting in my drafts for probably ever) they dated in HS briefly and both had their issues/neurosis/problems to deal with so they broke up and it wasn't the best break up either, and they grew separately for a few years, maybe dated other people, maybe were heart broken at times, but for SURE became the men they needed to be and rekindled. And from that, they reached the peak they needed to peak and it brings them back together. And then they can get married and I don't see them divorce. BUT then, I'm totally open to a scenario, especially in AUs where it happens lol! I just probably didn't envision it, but if you win me over with the dynamic and characterisation, I'll eat it gladly do not worry ehehe so let me know :3
