Kinda confused as to why people are saying Cabel is toxic... like he may be intimidating her with his aura but in my opinion he's been there for her when she needs it the most. He doesn't understand these socially situations because he's obviously isn't comfortable and prefers to keeps to himself, so he isn't used to it. In my opinion, as of right now Elvin isn't necessarily in love with her right now, but has an interest to her as someone completely different from what he's used to.
:/ peeved at the comments hating on any of the characters, I personally love how the story is taking its time developing the character's relationships. Go read some of the other isekais if you're looking for something shallow
