AU. Yukina is a pop singer and sings the theme for the anime adaptation of one of Kisa's titles. They meet and easily hit it off, but as Kisa learns, dating a famous singer involves a lot more mishaps than if you're not.

Takahashi Misaki works as a shadow singer for a Jpop icon who can't sing named Io(Shizuku Ishi). And when the great composer Usami Akihiko took a liking of the voice he heard in a performance, he took a liking of Io as well, not knowing that the voice he loved way back before was Misaki's.
