This doesn't have to do with marriage. But I was just thinking. Could you add a C-A for Caeldori/Selena? Seeing as Selena is literally Severa who was Cordelia's daughter. And Caeldori is a lot like Cordelia, I could see someone writing some interesting supports for them together.
Actually, I just looked it up and it turns out Caeldori can actually be Selena's daughter. So, they do have supports together. But their mother/daughter conversation is completely generic and makes no mention of the fact that Selena's daughter looks exactly like her own mother. It'd be cool if someone rewrote those. Or if you added non-mother/daughter supports for them. Because it would've been really interesting to see how Selena would react to a character looking just like her mother.
