"Wait, the owner's son wants to test our real-life mannequin? That's... problematic. We don't have any stock available right now," Ayano Kato says, visibly shocked. That day, an urgent request arrives from the owner's son, forcing her to deliver the company's most anticipated product of the year—an ultra-realistic mannequin she's been meticulously developing. After countless prototypes, this lifelike figure has finally reached completion, marking the season's biggest breakthrough. Angering the owner's son could delay the launch or even jeopardize the entire project. Faced with no other options, Ayano fixates on her wife's unexpected suggestion: "Send me instead of the mannequin!" It's a painful decision, but one that will ultimately set the story on an irreversible course.
