Yūto Matsubara, 27, works in sales for a major toy maker. Though employed in an industry built on imagination, he grapples with profound dissatisfaction. Having abandoned his personal dreams, a persistent hollowness haunts his daily routine. This disillusionment spills into his personal life, leading him to consciously relinquish any hope of a romantic relationship with Ai Minami, a woman suggested as his childhood sweetheart.

A pivotal moment arrives when a robot named "Time Driver," powered by the energy of dreams, suddenly materializes before him. Yūto is forcibly thrust into its cockpit. Inside, he comes face-to-face with a manifestation of his 12-year-old self – the pure embodiment of youthful aspirations and potential he long ago discarded. This encounter compels him to confront the jarring chasm between his unfulfilled adult reality and the hopeful dreams he cherished as a child.
