Kaori visits her daughter and son-in-law's apartment for the first time in a while, feeling emotional seeing her daughter seemingly happy. Eager to meet a grandchild soon, her hopes are dashed when her daughter suddenly frowns and retreats into the bedroom alone. Confused and distressed, Kaori is then told by her son-in-law that despite his attempts, they've never had sex—and worse, her daughter apparently dislikes sex altogether. Hearing him weakly whisper, "I want to, though..." fills Kaori with pity. Speechless, she stands frozen. One day, opening the bathroom door, she catches him holding her lingerie, gripping his crotch. Witnessing his silent suffering over her daughter's rejection, Kaori decides to keep it secret and gently reaches for his groin.
