■My Brother's Marriage, Hometown Swapping - A bold exchange of wives in front of my father-

His brothers (brother Ginji, younger brother Hiroshi) and his wife Miwako gathered at their parents' house during the large-scale renkyu. His father-in-law, Kiyoharu, lived in his parents' house, but recently he began to grow worried and gathered there. However, the couple spent a leisurely period of holidays, but behind them, they were intermingling the feelings of men and women. Hiroshi continued to think of her older brother's wife, Miwako, and Hiroshi's wife, Misa, was attracted by Ginji. And even though the couple repeated affairs, the behavior of their father-in-law broke each other's relationships.
