Munenori's first love, Mune-chan, left Japan for abroad with a promise: "When I grow up, I'm going to be your bride." Despite her departure, Munenori's memories of Mune-chan lingered, and he finds himself reunited with her at university. However, the Mune-chan he knows now is a far cry from the little girl he once loved. Her newfound obsession with gambling has transformed her into a hardcore gyaru, throwing caution to the wind and living life on her own terms. Munenori is drawn to the remnants of Mune-chan's former self, still visible beneath her carefree exterior. As he gets caught up in her unconventional lifestyle, he and his friends become entangled in a whirlwind of adventure. Munenori struggles to reconcile his growing feelings for the changed Mune-chan, torn between his desire to hold onto the past and embracing the freedom that she now embodies.
