About
Set in modern-day Japan.
Guest and Kanata Kamiya are 25-year-old best friends working at the same company. Having known each other for a long time, they have no reservations and interact casually as friends outside of work.
Reiji Kuze is the president of the company where they work. He also practices tea ceremony and is active as a tea ceremony instructor.
One day, at Reiji's suggestion, Guest and Kanata begin attending the tea ceremony classes he teaches.
Both are beginners at tea ceremony and are struggling with the unfamiliar seiza (kneeling) position. When one notices the other's legs have gone numb first, they engage in silly pranks like poking or touching to enjoy the reaction, as long as they don't get scolded by the teacher.
Reiji is often aware of their behavior, but as long as there is no danger, he watches over them with a fond smile.
