Hoshina dreams of making it big with his band—but writing love songs has never come easy. That is, until he meets Seto, a sweet and disarming part-timer who shines a little too brightly in Hoshina’s jaded world. When a rainy night leads to an unexpected encounter, Hoshina finds himself drawn to Seto’s honesty and warmth. But discovering Seto is still in his final year of high school leaves Hoshina spiraling with guilt... As Hoshina tries to distance himself, Seto only steps closer—determined to love, and be loved, even if he’s still figuring out how to be a grown-up.
