Hibiki, the bookworm who shuts herself in the library, and Naru, who is cheerful and has many friends. These two opposites spend their after-school time together in the library as a daily routine. However, thinking that she shouldn't hold Naru, who is good at sports, back, Hibiki decides to encourage her to join a sports club. Upon hearing this, Naru inadvertently confesses, "I don't want to waste the time we can be together. Because I like you, Hibiki!" This collection includes the title story "The World Exists for You" along with five other tales. It is a gem of a yuri short story collection by the author of "The Moon with a Missing Piece and Donuts," delicately portraying the fresh emotions of women.
