Yuta was busy doing household chores while her daughter-in-law was pregnant and returning home. I have lived alone for a long time, so cooking at home is not a pain, but I still feel lonely. When I missed such a person, my sister-in-law, Rin, came to see me. When the house became lively after a long time, Yuta welcomed Rin with a big welcome, but Rin's real purpose was to get rid of his frustration with Yuta.
