I'm watching this series now. Currently up to disk 2.
For now, I like Shuichi Nakatsu (orange haired soccer player) and Minami Nanba (2nd domitory's leader).
One thing I don't like about this series is the premise that Mizuki Ashiya indirectly causes Izumi Sano to injure his leg and lost the confidence to high jump, so, out of guilt she disguises as a boy to join the all-boys school to encourage him. That is so cliche! I would rather it follow the manga* and just has Ashiya join the school because she's crazy about Sano. Other than that, I'm satisfied with the drama.
*I have not read the manga, but read about the premise in wikipedia.
