You mean Arata vs Taichi, yes.

@episode 1: Enjoyable, but nothing special. I actually find myself rooting for Sumire in her quest of making Taichi fall for her. A beauty like Chihaya not realizing how pretty she is, is rather annoying. Itīs the kind of girls that get anything without having to put effort in it. Sumireīs "I want to have a choice, too!" made my like her.

And yes, obviously the grey haired first-year is gonna join the main cast.
