Kanon is on good terms with her husband and has built a happy family. Her husband's younger brother's house became uninhabitable due to a water failure, and she was taken care of by Kanon's house for a while. Kanon doesn't like his brother-in-law who looks at Kanon with gloomy and lustful eyes. He peeps into the bath and offends him and speaks ill of his brother-in-law to his husband. My brother-in-law, Kanon, who was indignant at hearing this, mixed an aphrodisiac with the black vinegar he always drinks.
