Miu Nomura is a 14-year-old 8th-grader who has been playing piano since early childhood. She grows up gradually while her friendship, kinship, and love affairs evolve around her, but those relationships inevitably affect her piano performance.
Miu Nomura is a talented, young pianist, but lately, she's having a lot of trouble focusing. She's got a crush on a boy a school, a moody teacher that might hate her, and she's lost interest in playing the piano. Luckily, she's also got her best friend Yuuki to help her out!
Mr. Shirikawa's interest in Miu's improvisational piece confuses her, but she's got other things to think about. It's her parents' anniversary and her mother is determined to have a wonderful evening. Her father has missed some of their previous anniversaries, but this time will be different... right?
Yuuki's emotions are running high! She's got a crush on the incredibly popular track star Takizawa. While Miu does her best to support her friend, she's still struggling with her own feelings for Takahashi as well as trying to get ready for her next piano lesson.
A confession?! Yuuki's trying to muster up the courage to tell Takizawa how she feels! But what if he rejects her? After all, Yuuki is a bit of a tomboy... maybe Takizawa likes more feminine girls? Meanwhile, a surprise announcement from Mr. Shirikawa has Miu a little flustered herself.
Yuuki's feeling bad for neglecting Miu. Will she be able to make it up to her? Meanwhile, Mr. Shirikawa's decision to place Miu in the spring recital is questioned by another instructor at the school. He insists it's for her own good... but how well does he really know his students?
Miu's sister, Akiko, has finally come home for a vacation! Akiko is full of energy and seems to be having a great time, but is she trying just a little too hard? Will Miu be able to get her to open up about what's really going on?
It's Christmas time and both Miu and Yuuki have a party to go to. It'll definitely be fun, but Miu's mind is on her upcoming recital... she's still not certain as to whether she wants to participate or not. That's not the only thing on her mind - Takahashi will be at the party as well!
While almost everyone is out enjoying New Year's, Miu's at home, hard at work trying to write her song. Things don't get any easier when she learns that Takahashi working so hard to get ready for his entrance exams that he's fallen ill. With Miu's worry now split between the recital and Takahashi... things are getting to be terribly difficult.
A deep despair has hit Miu. She's decided to give up not only the recital, but the piano and Takahashi as well. Angered by Miu's decision, Yuuki confronts her. Can she stop Miu from giving up on everything?
The day of the recital approaches, but there's still one person Miu has to invite: Takahashi. Will she be able to do it?
