She attempts to cover her body with vacuum cleaner hickeys, only to be scolded by her mother. While taking Kī to the library, Tomoko meets Kousaka, one of the boys she met while sheltering from the rain the other day, who Kī assumes to be Tomoko's boyfriend. The next day, they see him with another girl, prompting Kī to confront him, bringing Tomoko's bluff to light.
