Thanks, your comment made me realize that yeah, both of their feelings are valid and there's no reason to prioritize whose feelings are more important or were more hurt. Because I expected Keira to be understanding towards Erez, I got heated when she did the opposite and immediately thought she was in the wrong but now I realize that they both could've done things better and I was too quick to bash Keira without putting myself in her shoes. At the end, what matters most isn't who's hurting more, but the fact that they're both hurting because of each other and need to have a conversation.
Agreeing with users who actually understand Keira instead of only considering a male character feelings. Keira concept of a demon was only Cosette but to know there's another demon it took her aback, esp when the prior conversation was discussing the evil shit about Cosette, a demon. How can there be more than 2 and one is someone she trusted, was he using and manipulating her to his advantage?? All things racing in her mind must've of been scary.
All sense of security she has been building up has been completely destroyed. But the majority of mangago users don't understand that. Call Keria all the names you want what she reacted the correct way a person with trauma would have reacted.
Edit: I do want to say that yes, her reaction was harash but she was hurting BOTH OF THEM WERE HURTING. BOTH OF THEIR FEELINGS ARE VALID as someone said let's not prioritize one feelings over the other
