The characters are well-defined and original; it's really nice to see a series that contrasts a sophistocated, prideful character (Ayukawa) with a childish, straightforward one (Hikaru) instead of the usual tsundere/yandere/loli mashups. Even though there are a lot of unrealistic/escapist moments, it's kind of surprising to see that there's a lot of maturity in a shonen series like this. Kasuga learns not to make excuses in love, that he doesn't have to learn about Ayukawa's past to get along with her, and Ayukawa and Hikaru are reasonably forgiving. But it has its weaknesses. The anime doesn't do a convincing job of explaining why Kasuga can't justtell Hikaru to beat it, and they never really connect the way Kasuga and Ayukawa do. There are also a lot of filler episodes.
