Yes, yes, yes! I need to see what happens after Frederique's and Leopold's routes. I really liked the game, but it cut off at the most interesting points; we don't get to see the incestual relationship blossom, we don't get to see Leopold's rebellion, and we don't get to see if the Prince's anger outbursts continue after marriage (I know he had his reasons and all, but like Frederique said after we cause the argument during the concert, everyone showed their true colours, including the Prince. I can't wait to see his true colours during a darn rebellion of all things).
Most media, and especially VNs, do this, so don't feel bad; I truly did like the game. It's why all fairy tales end with "they lived happily ever after". But I saw this concept work wonderfully with another indie otome game, Seduce Me, and the sequel is truly a thing to behold after the more banal, but enjoyable, first game. I'd love to see it again here.
Keeping the romances allows two things: actually develop them (since in all VNs, by necessity, what we actually see if the path up to the relationship, and seldom the relationship itself. It almost always ends after the characters hooking up), and focusing more on the plot without thinking "how am I going to make the characters fall in love with this". Now it's easier to fit the romantic moments without having to contrive scenes to make them interact, since they are already living together. It's why Frederique's scenes felt more natural and less something I had to pursue, since you know, they're siblings, so he naturally seeked her out. I didn't have to magically know to go to the music room or the gallery. That leaves more room for the plot itself while not sacrificing on everything else.
Plus, I really, really want to see the mom. She played such a huge role in the first game, but only in spirit; I want to see her confront Frederique and Bastien especially. The scandal!
