This anime series is centred on Kazuhiko Nukumizu, a high-school boy who describes himself as a 'background character', and various female friends. He is a somewhat reserved character and the girls have one thing in common; Kazuhiko has witnessed them being dumped or rejected by boys. Over the course of the series he tries to help the girls in various ways.
I thought this was an enjoyable series. On the surface it looks like yet another harem show but it manages to do things differently. Rather than the typical stereotypes the characters and their issues feel real which gives in emotional heft while still being amusing at times. The character designs and animation are of a high quality. Overall I'd definitely recommend this to fans of the genre; when it was over I was left wanting more.
