In the middle of class at a certain school, Rumi Yokoi, a diligent student, has her in-class life turned upside down when her desk mate Toshinari Seki begins to play by himself at his desk in class. Although Rumi is irked by Toshinari's distracting yet intricate playtime, she finds herself being drawn into his interesting hobby. Never being able to focus, Rumi observes Seki's stunning ways of slacking off in class.

The boy who sits next to Yokoi in class, Seki-kun, is always up to something at his desk. He manages to somehow play very elaborate games without attracting the teacher's attention. From dominos, to shogi, to go, to mecha models, to playing with cats and more, he always has something new to do. Yokoi often finds herself getting reluctantly interested in his games, even though they always seem to end up getting HER in trouble with the teacher!

Shizuku and Tamami are geisha in Atami who are rivals at the same okiya (tea house). Shizuku is a miser who will use any tool necessary to get what she wants, including sex. On the other hand, Tamami believes in doing things the traditional way, with class. With opposing personalities, these two are always at each other’s throats. Tamami continues to blame herself for her mother’s suicide while Shizuku never knew parental love and doesn’t have good luck with men. Learning each other’s past, the two seem to have built a strong bond… that is until Kenzo, the event producer of the 2020 Tokyo Olympics comes to Atami. Kenzo will be making a movie about traditional Japanese culture for PR and would like to have either Shizuku or Tamami in it. Tamami sees this as an opportunity to fulfill her dead mother’s dreams, while Shizuku sees this as a path to getting rich. The two compete for who will get the contract for this dream opportunity.
