Nukumizu Kazuhiko, a loner with a love for light novels, accidentally sees popular Yanami Anna being rejected by her childhood friend. This leads to unexpected interactions with other seemingly defeated girls like Yakishio Lemon from the track team and Komari Chika from the literature club.

Lemon goes to the gym storage room to talk to Nukumizu. They get locked in but are rescued just before they pass out from the heat. Lemon's crush Mitsuki shows up at the nurse's office with a get well gift. Later, the two visit the lit club together...

Lemon and Yanami join the literature club. Pressured by the student council to demonstrate their club activities, Tamaki and Koto decide that everyone should write and submit web novels. The members head to the beach together for a weekend training camp.

Nukumizu endures a chaotic few days of being constantly distracted by his sister Kaju and Yanami. One afternoon, Yanami invites Nukumizu to a café and the two spot Lemon and Ayano hanging out together.

Lemon opens up to Nukumizu about her complex feelings for Ayano. She decides to clear things up with Ayano and Chihaya. She asks Nukumizu to escort her to her former elementary school at night to secretly meet Ayano and finally tell him the honest truth.

Nukumizu, Yanami, and Komari go to town to research a theme for their Tsuwabuki Festival exhibit. They successfully find a new club advisor and preparations seem to be going smoothly...

Nukumizu and friends manage to complete the literature club exhibit in time. Once the festival begins, the exhibit draws a constant stream of visitors. Yanami steps in to give Nukumizu and Komari a break to go explore the other events on campus together.

Komari practices her presentation for the club presidents' meeting, but still has trouble talking due to her intense fear of public speaking. Nukumizu tries to throw her a lifeline, but it turns into an argument and she runs away from him in frustration.

Yanami asks Nukumizu to arrange an adult date. As Yanami's old friends are gradually realizing that she doesn't actually have a steady boyfriend, she wants to maintain her charade with a fake date.
