Okay, that was a good chapter, after several that were rather revolting/creepy. Both characters seem real and relatable here, while still staying true to their established -- i.e. childish -- personalities.
He wants a sexual relationship with a "loving wife", but he doesn't want to do any of the emotional work of actually winning her heart. He just wants it to be given to him on a silver platter because he paid for it. That's clearly not gonna work. Meanwhile she wants to pretend that entering into a group marriage is just a legal technicality, and that she can continue live her life as a single person. That's not going to work, either.
Both of them need to grow up and learn to genuinely work together order to make this possible. It'll be interesting to see how and if they manage it.
