One evening, a husband brought home a male friend named Yamashita. Upon hearing the story, Yamashita was unemployed and living a lazy life of pachinko, yet the husband cheerfully laughed and served him drinks and snacks. The wife, Yukine, was inwardly displeased, but since he was her husband's friend, she reluctantly took care of the alcohol and appetizers. Then the husband said, "Yamashita, it seems he got kicked out of his apartment. I decided to let him stay here tonight," so Yukine reluctantly prepared a futon for the guest. But an unexpected turn of events awaited her there.
