On a weekend, Masatoshi, a hardworking office worker living in Tokyo, took a rare extended break and returned with his wife to her family home. After a three-hour journey by shinkansen and local trains from the city, they arrived at his wife's parents' house located in a mid-sized city undergoing urban development. Upon arrival, his wife's mother warmly welcomed them. As he saw her, Masatoshi found his eyes drawn to his voluptuous stepmother-in-law's shapely figure, letting out an involuntary sigh. Within the quiet atmosphere of the family home, an ordinary visit gradually turned into a time of new realizations and intimate healing.
