D.C. Girl's Symphony

On Hatsune Island the cherry blossoms never fall. High school student Shio lives with her step-brother Takaaki while her parents work abroad. When three brothers — twins Ryouhei and Kouhei, and their older brother Aoi — transfer to her school, every girl in class immediately takes notice. Shio's first impression of Ryouhei is specifically bad. The situation becomes more complicated when she hires a home tutor who turns out to be Kei, the eldest of the three brothers.
