The scholar has become frail and sick due to too much sex (involving two sisters-in-law who are bisexual and into S&M). He goes to the brothel for treatment, where he is offered the top courtesan. At first, husband and wife cannot recognize each other; she looks at his penis and thinks it cannot be her husband's because his is small; he cannot recognize her because his eyesight is failing. While they are having sex, he takes a close look at her figure and nipple and recognizes her. To her dismay, he screams, shouts and calls her a disgrace. To his dismay, she runs off and hangs herself. Yeung-Sheng, completely broken, goes back to the monk to ask for forgiveness.
