The drama kind of took a jump here, didn't it?
Hell, it went pretty straightforward. I would have rather if the mangaka had maintained the same slow but ominous pace it had before.
Poor Kujirai. Part of me just wants her to leave town and live a life that's complete separate from Kujari-B's after that exchange, where there's no constant reminders that she isn't her past self.
Y’all she’s a clone of her past self, so it is her, but not *her*. So the guy fell in love with her past self so he hates that he’s slowly digging her new assumed clone self. That’s why he says he hates her.
