A man started living alone in a Tokyo apartment for his university life. One day, he went out to the balcony and found a pair of panties that had been hung out to dry by his neighbor this morning lying on the ground. He quickly took them back to his neighbor, only to be greeted by a half-naked beautiful wife, Yuino. From that day on, his dream-like apartment life began. He could see Yuino changing clothes from the balcony, catch glimpses of her panties while she was cleaning, or witness her intense kisses with her husband... And then one lewd incident after another occurred...
