The housewife had long struggled to balance family life and her career. Working as a nurse while juggling housework and childcare, she had been content with her married life. But before she realized it, 15 years had passed—her children had grown, and she had aged too. Though she truly believed her life was happy, an unsettled emotion had quietly begun to stir within her, growing impossible to suppress. It wasn't regret, but an overwhelming, helpless feeling tightening her chest. The more she tried to push it away, the stronger it became. Before she knew it, she found herself traveling with a stranger. That first night with a man she'd just met left the housewife emotionally shaken, enveloped in a flood of new sensations.
