There was a family of three boys and four fathers living together, and next to them was Ryoko, a beautiful widow who lost her husband two years ago. They have known each other since their spouses were alive and well, and there are no barriers between their homes. One day, Ryoko goes to her neighbor's house with a souvenir from her trip in her hand. Inside, she discovers Ryoko's panties, which she thought had been lost. Her neighbour's third son apologizes to her embarrassedly. I intended to put this matter away because it was a secret between the two of us, but the good relationship between the two families was about to crumble...
