Nana has been married to a tea ceremony / Sagawa style Aida school house for two years. After learning the tea ceremony after getting married, he was finally recognized as a full-fledged person and was allowed to practice at the Iemoto Sagawa Ginji. On the day, Nana behaves as Ginji tea, but she is so nervous that she accidentally breaks the heirloom bowl. Ginji, who apologizes to Nana for not being able to get rid of the bugs in her stomach, proposes a stay-in practice as a condition to allow. Ginji suddenly ordered Nana to take off her kimono, saying, "I'll teach you the essence of the tea ceremony."
