Ashita, Hadashi de Koi.

“Stay with me this time.” On the day of his high school graduation, the protagonist looks back on three deeply unremarkable years. His grades were poor, he had long since abandoned his dreams, and his relationship had fallen apart. His ex-girlfriend, Chika Nito, has since risen to fame as a celebrated musician, leaving him far behind in her shadow. Yet, just as he reflects on his failures, Chika suddenly vanishes without explanation, and the world around him shifts into an entirely unfamiliar reality. Stunned and disoriented, he soon realizes he has traveled back in time to the very day of his high school entrance ceremony. Armed with the knowledge of what is to come, he resolves to change everything. Simply saving Chika from her mysterious fate is no longer enough; he refuses to remain the inadequate person he once was. This time, he intends to stand beside her as a true equal. Determined to rewrite the next three years through sheer effort, he sets out to forge a future where they can walk side by side. What begins on the final day of high school transforms into a profound second chance—a story of youth, redemption, and love rekindled from the very start.
