Keiko, who was frustrated every day because of her husband who often does not go home for work, was spending every day comforting her aching body with a sigh. One day, my son brought a man named Hashimoto, a senior who became friends with a part-time job, to his house. Keiko, her mother, was relieved to see her son, who hadn't had many friends until now, forgiving Hashimoto, and accepted Hashimoto as warmly as his son. At one point, Hashimoto eavesdrops on the telephone conversation between Keiko and her husband, and finds out about Keiko's frustration and suddenly changes her attitude.
