I just want to know if they pair up nicely or not. I got them to S rank and now that "Support" is highlighted, it drives the OCD side of me crazy: I already can't deal with the S-rank between MU and Olivia...
Virion gets whipped pretty badly, they have good chemistry though. There aren't any true canon couples (except maybe Chrom and Sumia ewwwgh) so pair up whoever you like.
Chroms relationship is the only one with any kind of story significance.
I realize that pairing up is really just for... lulz... but I still like to pretend that they'd be happy together. Yeah, I saw their S rank and he does get whipped... But I can't tell if that's good or bad for someone like him.
Story-wise? Same as any other pairing. Stat-wise? Average child. No reason not to do it, tbh.
Virion's main purpose in the story is to get trampled by other characters. A lot of his supports(Cherche, Fred, Maribelle, etc) involve being put down by other characters. Hell, even Olivia gives him some lip. OLIVIA. He's just that guy.
Point: He's gonna get whipped by most of his potential wives anyway. At least with Sully he knew what he was getting into.
