From Day of the River:

An unhealthy obsession with boys' hands, voices, and other things. Protagonist Mizuhara Hiyori has a difficult-to-explain fetish. In order to live a peaceful life, she hides her fetish away from the world and entered Blue Star Academy. There, she meets Narita Naohisa, a beautiful boy who discovers her fetish one day at school. How? Because he possesses all of the lovely qualities that Hiyori fetishizes! However, Narita-kun turns out to be a rather troublesome teenager...

Honori joined the suspicious-fun club, the "Substitute Club", which substitutes for people and does their work for them. The members of this handy-man type club are very free-willed and loyal to their desires.

Kotori-chan and Hi-chan promised to marry each other when they grow up. But 10 years forward, the only one who’s actually “grown” is Kotori-chan, while Hi-chan still looks like a grade schooler. Hilarity ensues.

The comedy story follows Mai and Kurumi — two polar opposites who act friendly onstage as the hit singing duo "Star Berry," but bicker offstage. What Mai really wants to become is a rock singer, but the easily flustered Kurumi would rather sing idol songs.

Asaichi can't play any instruments and his voice is average, and he's only in a band for the girls and the sex. Plus, he's homophobic. For some reason the new bassist Yoru is infatuated with him despite the treatment Asaichi gives him.

Included "Aru Otoko no Uta": the story of yakuza Onii chan and how he had come to know Yoru.
