I never liked Momo, not once. She's beyond obsessive, and too close minded. Can't see anything beyond Chi.
It was pretty sweet when Nitori asked could he work at the bar. And although I do like Takatsuki the way she is now, I preferred her the way she was before. But then again, she's probably just growing up, and the confession to her just drives the point home.
Hopefully we'll find out more about the sad!confession in the next chapter.
