Ria, a married woman who lives in two households with her husband's parents. Her brother-in-law, who had a large amount of debt due to her marriage fraud, came home temporarily. One night, his brother-in-law, who has lost all of his work and private life, notices the voice of his brother and his wife's night activities, and feels anguished towards his sister-in-law. My brother-in-law lost his reason when his sweaty body was dazzling in the sweltering summer heat.
