Honestly ren sucks in my opinion. I completely feel bad for Hina. I don't agree with some of her actions, but I do feel bad. She's being bullied, I doubt her parents even know, she has no friends and no one to help her. With her mind like that and then the pain of having a friend/crush who doesn't really like you, only uses you, her mental state might be on the edge.
The first one was terrible in my opinion. The prince was an asshole who decided to test his fiancees feelings. He tricked and deceived her and possibly publicly humiliated her then humiliated another girl in return as well.
The second story, I adore it. The sisterly bond I never get to see in any isekai stories. Then the "heroine" who is smart enough not to choose any one of the guys. (By the way, wtf a teacher proposing to a student?!) Not to mention it didn't seem like the mom hated the commoner or her daughter which was just the sweetest. They all understood how selfish and rude the count was. 10/10
Iris has more drama in her life compared to the amount of drama happening in the entire kingdom
