Part of the series of educational videos that teaches kids and young adults several basic tax lessons.

Tightly clutching his Gibson guitar, Mafuyu Satou steps out of his dark apartment to begin another day of his high school life. While taking a nap in a quiet spot on the gymnasium staircase, he has a chance encounter with fellow student Ritsuka Uenoyama, who berates him for letting his guitar's strings rust and break. Noticing Uenoyama's knowledge of the instrument, Satou pleads for him to fix it and to teach him how to play. Uenoyama eventually agrees and invites him to sit in on a jam session with his two band mates: bassist Haruki Nakayama and drummer Akihiko Kaji. Satou's voice is strikingly beautiful, filling Uenoyama with the determination to make Satou the lead singer of the band. Though reticent at first, Satou takes the offer after an emotional meeting with an old friend. With the support of his new friends, Satou must not only learn how to play guitar, but also come to terms with the mysterious circumstances that led him to be its owner.

The band given—comprised of Ritsuka Uenoyama, Mafuyu Satou, Haruki Nakayama, and Akihiko Kaji—has advanced to the final screening of the Countdown-fes Amateur Contest, in which they will be judged on their live act. Although enthusiastic, they worry about having only one original song to perform. Mafuyu embraces the idea of learning more about music in order to create new, emotionally resonant songs. In this regard, he unexpectedly receives help from Ugetsu Murata, Akihiko's on-again, off-again lover. Ugetsu has unsuccessfully tried to let go of Akihiko, who himself is torn between lingering feelings for his past and an uncertain resolve for the future. As the competition draws near, Haruki uncharacteristically begins to doubt his place in the band and the trust he shares with Akihiko. It is a given that not all attachments last forever, but it remains to be seen what can be salvaged from the ruins of heartbreak—or if only regrets will endure.
