Young husband arranged for his wife to return to her hometown hospital for childbirth, temporarily leaving the house vacant. Overwhelmed by the daily grind at work, he felt a quiet sense of nostalgia at living alone again and bid his wife farewell with a smile. One day, his wife's friend Mirai visited. Hearing that his wife was struggling with household chores and personal care during her stay at her parents' home, Mirai had come all the way to help out. While grateful, the husband found himself drawn to Mirai's fresh, alluring body, and an awkward tension began to fill the air.
