Mourning wife's pantyhose

My father-in-law's third anniversary. Reimi visits her husband's parents' house, now only his brother-in-law. His brother-in-law couldn't get a regular job, and he constantly had a fight with his younger brother, Reimi's husband, and his relatives were criticized as a irresistible older brother. Meanwhile, her husband suddenly returns to Tokyo due to work problems, and Reimi, who is left behind, becomes an outlet for her brother-in-law's inferiority complex.
