Yuki lived a quiet life in a rural town when a new neighbor moved in next door. Her name was Hitomi. Yuki quickly became close with her after Hitomi came by to introduce herself. Wanting someone to confide in, Yuki began opening up about her husband's infidelity. "Your husband must be an idiot to neglect such a beautiful wife," Hitomi said, then kissed Yuki passionately. Surprised by the sudden kiss, Yuki was overwhelmed by Hitomi's tenderness and the unfamiliar pleasure she felt, surrendering her body completely. After that, whenever Yuki thought of Hitomi, an unbearable ache stirred within her, and their intimate relationship grew deeper and more intense.
