That was Quite a Performance.

Eugene, an American exchange student who had become interested in Japanese culture, mistakenly thought the tea ceremony club was a martial art like kendo or judo , which he had recently seen, and wanted to observe. Torii Itsuki , who happened to be nearby in the staff room, was asked by the tea ceremony club advisor to show Eugene to the tea room . Itsuki only intended to show him around and leave, but he was caught by the club president and ended up participating in a tea ceremony himself. While the president was preparing the tea, Eugene realized his mistake and said, "We can have a tea party at home, I don't see the value in this at all," and tried to leave. Perhaps offended by his words, Itsuki told Eugene to drink the tea he would prepare next before he left. After drinking the tea, Eugene shed tears without understanding why, and remembered his hometown and friends. On the way home, Eugene asked Itsuki to be his friend, but Itsuki gave him a cold response. The next day, Eugene joins the tea ceremony club and learns from the advisor that Itsuki is the son of a famous local tea ceremony master. He asks Itsuki to be his coach, but Itsuki refuses, saying he has no time for the club because he is seriously dedicated to his practice at home. To show his own serious commitment, Eugene vows to learn the "otemai" (tea ceremony), but is given a deadline: the next day to teach Itsuki. Eugene practices as much as he can with the club president, reads the English tea ceremony textbook provided by the advisor late into the night, and approaches the "otemai" with dark circles under his eyes . Itsuki, who has felt lonely since childhood because Eugene always prioritized his practice, is moved by Eugene's spirit and joins the tea ceremony club. Two more girls join the tea ceremony club, and they work hard towards events such as the sports festival and cultural festival , learning through trial and error.
