Because technically, if they aren't married properly, their children wouldn't be Satou's heirs and would illigitmate. Not to mention it isn't considered "classy" to have a relationship with a noble lady and not be married to her.

What's more, it could endanger any future arrangement of Satou's wives, as there is a "hierarchy" on the wives among royalty and upper noblity. Hence why Soltrick couldn't marry Maryest, and instead she was instead proposed to Satou. This is also why Seiryuu isn't in a rush to marry Zena to Satou, because even if Zena was adopted by the Earl, her position would be below wives like Sistina.

The latter point is a real concern, especially for Sistina, hence why she was upset with Sera flirting with Satou when she is "below" herself and Mito in terms of "hierarchy", believing Satou has a "duty" to her and Mito before he falls for Sera.
