The chapter opens with a flashback to the previous chapter, where we learn that the president of a client company has had sex with a secretary named Kishujima, who is also the secretary of another client company. The flashback is interrupted by the arrival of the new secretary, who introduces herself as "Satsuki." She explains that she is the half-sister of the president and that she was born in the United States. The two of them call each other "stsuki," which means "half-sister." The new secretary explains that her father might have misheard her name and made her mispronounce her father's first name. She also explains that the previous dinner meeting she had with the client company's president was actually her lover.
