Saito, who got married just six months ago, leads a serious life as a pharmacist and embodies the typical reserved science-minded woman. Her decision to appear in an adult video stems from an unexpected reason. Naturally shy with few friends, she had a quiet and uneventful youth, which made her desire a personal transformation. She met her husband at a mixer—the first one she'd ever attended as an adult—and quickly bonded with him, leading to marriage. However, after discovering that her husband has been cheating with a woman from the nightlife industry, she began questioning whether she lacked enough allure or charm to keep his interest. Driven by this pain, she embarks on a journey to reinvent herself, hoping to win back her husband's affection through self-improvement and newfound confidence.
