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...

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.

Nukumizu gets grilled by Ayano after being caught together with Chihaya. Nukumizu clears things up, but then for whatever reason Nukumizu, Ayano, Chihaya, Lemon, and Yanami end up 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.

Having settled on "Edible Readings" for the literature club exhibit, Nukumizu and Komari continue preparing for the Tsuwabuki Festival. When the two stop by the local library to return some reference books, they notice Tamaki and Koto on a date together.

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.
