Point of view: Chidori is better than Sonozaki and that's why !!!
Chidori always loves to be with Katsuhira even before he cares about himself. She is kind to him and understands him much better than Sonuzaki. Her story is so mysterious yet. Chidori is infatuated with Katsuhira, but for Sonozaki the situation is different so I doubt she will have any interest in him. Nevertheless, he remains a terrible character. In addition to all this, I helped Chidori Katsuhira Shui keep his psychological side healthy and keep him calm all the time.
I can change my mind after completing the anime and see the rest of the story.
