Spoiler!
I hate this part of the story. They need the most powerful men (not family) available, so yes... Obviously they do convince the MC to *do it* with her. He doesn't want to because of the girl (forgot her name) he already loves. And she does protest but ends up agreeing. The part that *personally* bothers me is that in the novel they don't just do it ... They do it HARD, I mean they end up breaking the whole room and the roof, wich I wouldn't mind if she wasn't unconscious... U know?. The girl fights back (the white hair girl) and halfway ends up enjoying it(?). A little bit rapie for me. And everybody is relatively near, so they hear it. Idk. And immediately after she has feelings and tries to be his second wife or something and later on he does have some kinda feelings but loves the original girl more. Idk how it ends, left the novel a little bit after the next arc.
