Plot

edit

Haruto Mizushima, a second-year high school student, secretly enjoys writing poetry, which he considers a gloomy hobby. After losing his parents in an accident during childhood, he lives with his grandparents.

One day, while submitting a piece for a literary contest, his poem is read aloud by a teacher and overheard by his classmate Ayane Tōsaka. Moved by his words, Ayane asks him to write lyrics for her, and the two begin collaborating on songs in an abandoned clubroom after school.

Haruto gradually learns that Ayane has developmental dyslexia, yet possesses remarkable talent in composition and singing. As they continue creating music together, they grow closer and develop romantic feelings for each other.

As their music gains attention, they face social pressure and isolation. Ayane eventually passes an audition and moves to Tokyo to pursue her debut, leading to a temporary separation.

Years later, they reunite at a concert and confess their feelings. However, Ayane is soon diagnosed with a serious illness with limited life expectancy.

In her final days, the two marry and have a daughter, Haruka. After Ayane's passing, her music and hopes live on through their child.[5]
