My sister-in-law, Miho, was kind to my brother-in-law who had a narrow shoulder because he didn't get a good job. On a tropical night in the middle of summer, my brother-in-law, who looked into the activities of his brother and his wife, committed Miho unbearably. What is Miho's reaction when he decides to leave home because he can't stand his own mistakes? A man and a woman who meet in a sweaty night drown in a dense love! ! !
