My daughter-in-law, Lisa, was about to give birth and was returning to her parents' house. Kenichi was worried about Lisa's older sister, Yumiko, who visited her one day while feeling inconvenienced, remembering her bachelorhood and enjoying her life alone. "It's okay because I can manage my house." There was a reason to refuse Yumiko. I was attracted to Yumiko as the opposite sex and was not confident that I could suppress my instinct. "Isn't it accumulating?" Yumiko said something that could be taken as a temptation, whether she knew or didn't know Kenichi's feelings.
