I find it hilarious that all of the named characters that did/do track and field with Kase apparently have a crush on her. First it was Aikawa, then Fukami, and now even Inoue got pretty flustered at the idea of her and Kase sharing a room. And of course Kase's never going to notice, since she's just so goddamn in love with Yamada.
(Okay, calling them crushes might be a bit of a stretch but I still find it funny)
