The Literature Club is Natsuo Fujii's club in Akamori High School. The club itself plays a central element in the story of Domestic na Kanojo. The Literature Club started off as a single person club with Miu Asihara with the club adviser being the legendary writer Reiji Kiriya. Kiriya spots Natsuo trying to steal a book and forces him to join the club, with Rui and Momo following suit the club begins.

The club plays an important part inside the story being both a center of love drama, but also being a place with long lasting bonds of friendships that have endured heartbreaks and will prove to play important friends into the future.
