Yes, I fully agree with you!! It would be really great if he ended up choosing Kinosaki because honestly he feels and seems like the better choice. Or it'd be crazy if he didn't end up with any at all lol which would be useless with all the buildup it has with the rest of the characters (Kinosaki included).
Considering the theme of this story is about finding the one you love rather than continuing the bloodline, I feel like Kinosaki is a great thematic choice. If Gero chooses Kinosaki, then it would really feel like it was a decision made out of love rather than compliance.
I get that anyone Gero chooses will 100% be his own will at the end of the story, but considering how his clan wants an heir, it feels like he'll be doing what they want at the end of the day, and ngl, it feels bad when a family that would have forced their daughter who loves women to bear a child with a man she's not attracted to "wins".
I feel like the story will go down the direction of Gero taking down his bloodline regardless because of how disgusting they are in general, but with Kinosaki by his side, at least in my opinion, it would serve as another motivator for Gero to create a change. The story started with Kinosaki, so it would be nice if the story ended with Kinosaki too.
