The Ethics of Anger

A female college student was suddenly killed, and four men related to her were suspected. They were the policeman Zhengxun who had an unrequited love for the female student, the loan shark owner Myeong-rok who had lent money to the deceased, the deceased's ex-boyfriend Hyun-soo, and the professor Xiu-ze who had an extramarital affair with the deceased. While these people were scrambling to defend themselves, the figure of a woman gradually became clear. She was Xiuze's wife Shanhua.
