Miu Nomura once loved to play the piano. As a little girl, the music made her heart soar and she eagerly shared her songs with all of those around her. Now an introverted teenager, Miu has become too shy to express her feelings - even through her music. Her playing has suffered and her piano teacher, the moody Mr. Shirakawa, has become impatient with her inability to reach the next level. When Miu develops a crush on upperclassman Takahashi, her best friend Yuuki is the first to notice. Unfortunately, Yuuki's too distracted with her own emotional troubles - she's fallen hard for third year track star Takizawa!
