Banri's amnesia isn't the plot; it's the permission slip. He gets to be someone new in Tokyo, and the show actually follows what that costs, the moment you stop running from your past, it catches up. Kouko barrels into his life demanding he choose between the person he's becoming and the person he was, and the show refuses to make that a clean answer. By the end, you're not watching a love triangle resolve. You're watching two people negotiate whether love can survive the person you become when nobody's looking.
Banri wakes up with no memory of who he was before a terrible accident robbed him of his past. Rather than stay trapped in his hometown, he accepts a fresh start at law school in Tokyo alongside his new friend Mitsuo. The city promises anonymity and reinvention, a chance to build himself from scratch without the weight of who he used to be. Then Kouko crashes into his life with the force of a typhoon. Beautiful, dramatic, and completely unpredictable, she upends whatever equilibrium Banri was starting to find. As the school year unfolds, he navigates the messy reality of young adulthood: making genuine connections, falling in love for the first time, surviving humiliation and heartbreak, and slowly discovering that moving forward doesn't mean forgetting. College becomes a crucible where Banri learns that reinvention isn't about erasing yourself, but about becoming someone worth remembering. His amnesia transforms from a tragedy into an unexpected gift, though one that keeps testing what he's willing to risk for a future he actually wants.
