Miu Nomura loves to play the piano, which she has done since she was a little girl. Once she grows into a teenager, she has to deal with all kinds of new feelings, most of which are triggered by her upperclassman Takahashi, for whom she harbors a deep crush. She is way too shy and introverted though to approach him, but she gets help from Yuuki, who is her best friend by far. Yuuki is a sporty and outgoing girl who is on the same school track team as Takahashi and her own crush, Takizawa.
Piano: The Melody of a Young Girl's Heart, consisting of 10 episodes which aired in 2002, deals with Miu's development into a young woman. It mainly depicts her struggle with her inability to show her emotions, which even starts affecting her piano-playing. Through up and downs in her relationships with her piano teacher, her family and her friends, she finds out what her music and the people around her mean to her.
