What do Shuchiin Academy's model students do outside of their student council duties? After a visit to the swimming pool, Kaguya Shinomiya and Chika Fujiwara take to the showers to wash themselves off. When Chika accidentally drops a bar of soap, the two find themselves in a rather slippery mishap. Meanwhile, Miyuki Shirogane and Yuu Ishigami examine a discarded pornographic magazine—its content bearing an uncanny resemblance to the other student council members. Later on, an intense fried rice cook-off commences as Chika and Miko Iino seek to crown a master chef amongst the council. These eccentric activities reveal a side of the student council that has never been seen before!

Every Thursday, Shuchiin Academy student council secretary Yuu Ishigami can be found in a state of anxiety. He counts down the hours until he can escape to the student council chamber to read the latest chapter of the popular seinen manga series, "Momo Doesn't Think." Joining Ishigami in his weekly reading, student council president Miyuki Shirogane swiftly grows excited at the news of a third season of the manga's anime adaptation. However, it is only a matter of time before vice president Kaguya Shinomiya discovers what has been engrossing the two boys. With the stigma of being labeled an otaku looming over his head, Shirogane must do everything he can to keep his embarrassing secret from coming to light.
