I am approaching my fourth year of marriage with my husband.She now lives in her husband's family home.At first, I lived with my mother-in-law, but after her sudden death a year ago, I lived with my husband.Suddenly, a person who claimed to be her husband's father appeared, shaking her peaceful life with her husband.We kindly welcomed my father-in-law, who told me to leave him at home until he found a job, but his appearance became strange day by day, such as wandering around the house in almost naked clothes and looking into the bathroom.
