Early in the morning Fujitaka and Touya stand over Sakura as she is in bed. Sakura doesn't seem to have a fever but she seems weary. After a short discussion, she convinces her father that she is just sleepy and that he should go to work. Touya decides to attend school even though he is really concerned about Sakura as well. After leaving the room, while in the hallway, Fujitaka and Touya both agree to come home early after work and school.

While Sakura is at home resting, Rika, Naoko, and Chiharu express their concern for her during home economics at Tomoeda Elementary. It is at this time that Tomoyo asks Syaoran if he wants to go and visit Sakura after school with her. He agrees as classmates admire Eriol's cooking skills. Meanwhile at Seijyo High, Touya wonders if Sakura is feeling any better. Then Yukito enters the classroom with a large brown paperbag of food. Touya begins to explain to Yukito something that he may not have realized about himself, but once again Nakuru manages to interrupt.

After school Tomoyo and Syaoran arrive at the Kinomoto residence. They have tea in Sakura's room and share the cupcakes that Tomoyo made in home economics. They wonder why Sakura couldn't wake up that morning. Kero explains to them that it is easy to use Clow Cards because they already have Clow's magic embedded into them, therefore, Sakura became exhausted by creating a new card because it required a great deal of magic. After this explanation, Tomoyo suggests that they call the new cards "Sakura" cards. Kero then goes on to say that he is worried because the only people who can command himself and Yue are Sakura and Clow Reed.

At school the next day Sakura writes to Ms. Mizuki in order to keep her updated on the most recent events. Upon writing, Sakura hears music being played. She glances into the classroom and notices that Eriol is playing the piano. Sakura then joins him in the classroom and listens to him play a song that Tomoyo has been practicing for an upcoming concert. A few moments later, Tomoyo enters the room and sings as Eriol plays the piano.

Sakura and Syaoran stay late after school to accompany Tomoyo. As they walk down the hallway they think about Clow's prescence. A few seconds later they hear Tomoyo's voice accompanied by a loud crash. Sakura runs and slides the classroom door open. Tomoyo is against the wall as the piano begins to hover in the air. Syaoran, Sakura, and Tomoyo run into the hallway to escape the dangerous piano. Syaoran uses his thunder call to temporarily stun the piano. Tomoyo suggests that every time it hears her voice it comes after them. After listening to this suggestion, Sakura develops an idea.

Sakura, Tomoyo, and Syaoran make their way to the roof of Tomoeda Elementary. As Tomoyo begins to sing, the piano follows the sound. When Sakura hears the sound of the piano banging on the roof door she immediately summons her Star Wand and transforms the Song card. The Song hovers in the air just a few feet from outside the fence. The dangerous piano tries to reach the Song card by breaking through the fence, but misses and falls to its demise.
