On the eve of the completion of the world's first hyper-realistic mannequin indistinguishable from a real human, Mio Kimijima was entrusted with a career-defining project crucial to the company's future. However, she was horrified to discover that the mannequin, scheduled to arrive from the United States the day before the presentation, had not arrived. Facing the biggest crisis of her corporate life, crushed by an irreversible mistake and on the verge of collapse, her wife suddenly made an unexpected proposal. It was an extraordinary and desperate resolution—made out of love for her husband and their marriage. "...Let me become the mannequin. If it's supposed to be that realistic, no one will notice the difference, right?" Hesitant and stunned, Mio Kimijima ultimately understood his wife's devotion and accepted her offer. In that moment, the story took a dramatic new turn.
