Well... at this point it's like... the hero totally sees them as game characters for him to do a dating sim with which is gross but also, he's saying the things i've been saying in this comments' section the whole time and the mc's reactions are honestly weird at this point so I don't think she's being entirely fair in her estimation of the hero either.
It's mostly the lack of communication that's bothering me at this point. We get it you like your fiance, and he was under mind control when he trampled over your feelings so it's all good *Grumble grumble*, have a conversation with him already! Don't do this wishy washy s*t when the end result's already clear, that's just asking to frustrate the readers! Same with the hero, it's pretty obvious the mc is a reincarnator from how she knew he was coming, talk to him about who he actually is, the fact you're a real person, what he knows about future events, something! These characters are so frustrating. The only one who's doing a good job with her role is the mind raping villainess and she's offscreen.
