This really is crazy though. Like, this chapter didn't reveal anything new about Hebikawa. I don't understand how this suddenly changes people's opinions of her. She has been the same as she always has, shitty and two-faced. And then she's putting the blame on MC saying "he wasn't seeing her for who she is", which is shitty and two-faced.
I mean, when you're actively deceiving someone by treating them nicely when in reality you find them disgusting, how are you going to blame them and make them think it's their fault that they misunderstood that? Isn't this textbook gaslighting? What? Hello everyone? She doesn't owe MC anything obviously but she sure as hell cannot tell him he never saw her properly when she was actively deceiving him for her own benefit
