This is exactly how this relationship would turn out. The second Florian makes her feel a little insecure or wants to stop battling, she would do absolutely anything to keep him. Using her body to trap him in a relationship for life is her best option at that point. If Juliana goes both ways, she would probably do the same thing to the female protagonist in the other possible reality.

The Best Nemona doujin ever. Of all Time. We need more Florina/Nemona.
