Okay but I swore the bitch prince liked the bitch cousin right???

I don't think he really liked her for who she was. More like she was a pretty trophy wife who brought him political support with her new last name and her position. He would've never chosen her without the name and wealth. Which is why the MC refuses to adopt her into her family this time. We'll see how much he'll stay with her without any advantages...He's a fucking leech! Both of them are, actually.
In the end bitch priest is probably like "why is him hypnosis not working"
