Carrying on from my previous comment about this "Chase after Emma" stuff, maybe I just don't like Emma at all. He was out of line, dancing is about matching your partner, but slapping him in front of everyone was a bit much. She could've just stopped.
And her being all scared after her speech about fighting together? And not even telling him about the note/calling card?
One of the few cases (for me) were first girl is NOT best girl despite how much more attention she gets compared to the others. Sorry, I'm just ranting, but this is all really frustrating me. I really hope he doesn't end up with her, or at least only her (this is a harem after all).
