Miki, a high school student born and raised in Kyoto, knows very little about how to have fun. Her classmate Aya seeks to change this, with the reluctant help of another classmate, Midori.

Student council vice-chair Ren wants to bring Midori into the student council, but Midori declines, saying she has other priorities. Ren follows Midori to her workplace after school to find out what it is Midori is so passionate about.

Maki finds Miki without anything to do, so they decide to hang out for the day. Meanwhile, as the school festival gets closer, students plan various events to spice up the festival.
