Just to play the Devil's Advocate (I know better than to expect psychological realism from Chinese Cartoons by default) it's not necessarily that Kurokawa suddenly overcame her issues with the magical power of Teen Drama. Rather, Miki and Izumi got her out of her dark hole of solipsistic self-loathing enough for her to realise just how dirty she done did Nanaki and focus on doing something about that instead.
The root of the problem is still there but she's no longer wallowing in her issues blind to her surroundings, and it's probably started dawning on her she has real problems that are also hurting other people she cares about. Which would of course be the first step towards getting better.
Well, it's up to the next chapters to clarify whether we're actually getting some proper depth here or if le DrAmAtIc ClImAx and ~Twue✿Wuv~ are magical panaceas to a lifetime of pathological self-image issues...
