Welcome to Momoko's waking nightmare. Things were settled, they were! She was SUPPOSED to have gone to a normal school, made normal friends, and led a blissfully normal life. But the universe is just cruelly, irredeemably, monstrously unfair, so instead she found herself thrown out of home, stuck in an all-boys boarding school with a roommate she hates, cursed with a hideous haircut and wearing clothes which, to be frank, she wouldn't be seen dead in. And the only thing worse than her current situation is the one that she'll be in if anyone ever realizes that she is, in fact, a girl. Everything is wrong! Particularly the fact that, even though she's surrounded by amazingly gorgeous guys, her chances of romance are less than zero. But with life this complicated, something's bound to give - and so it does.

But one question from Chisato's childhood friend, Takahiro, brings the past echoing back with more clarity than ever before.

3) Voice of Mine
Inagaki Shuu is a musical genius, the son of musical geniuses, and so the eyes that watch him as he plays the violin are not the eyes of attentive listeners, but the eyes of scrutinizing customers.
