Haruto is a university student who struggles with a sense of unease or dissatisfaction in his daily life. He has never been particularly invested in music, usually just listening to whatever autoplay serves him, until he discovers the live performances of a singer named Rio. Attending Rio's monthly shows becomes his sole source of purpose and escape. One evening after a concert, Haruto finds himself at a bar where Rio happens to stop by. The chance encounter allows Haruto to see a side of the musician that he could never glimpse from the audience—a more private, vulnerable, and human dimension. As Haruto learns more about Rio's personality and life beyond the stage, his admiration deepens into something more personal and intimate. The story weaves together music, human drama, and the gradual development of a romantic connection between the two, unfolding across four chapters that trace the shift from distant fan worship to a closer, more complex relationship.
