Six months ago, Chiyuki's daughter and her boyfriend came to visit to announce their engagement. During the visit, they suggested living together, and since Chiyuki had lost her husband, she felt reassured and happily agreed. From that point on, a shared household life began between Chiyuki and her daughter's couple. However, ever since then, Chiyuki has frequently felt restless due to the couple's nightly activities happening upstairs. After half a year, both the daughter and son-in-law have become increasingly occupied with work and social outings, often spending time apart. One day, noticing that her son-in-law is alone in the room, Chiyuki can no longer restrain herself. Hesitantly, she initiates an intimate encounter. The desire to be held, even just once, grows too strong to suppress.
