@Dante well i think he acted like that, because he rememerd the old conversation he had with her about the romance book, where the prince forces a kiss Onto a woman. There she said he should do that to her and thats the reason why he acted line he did. (Still no excuse to do that sh**, but anyways) Hope you have a good day.
@Misaka would have accepted that explanation but why now send if we have to think about the order
Fiance> to commoner girl> then he found a more prettier woman( MC)
He switched 2 different girls if you found a more prettier girl, he would have switched again. So I do not like how they try to make it not his fault. Why he acted like that
