Kakei Kyoutarou, the hero, is a seemingly ordinary high school student, but he can predict what will happen in the near future. However, he has no expressive ability, but as a member of the book club, he leads an unremarkable life. However, there are scenes of cherry blossoms, Misono Senri, Suzuki Kana and other peaks around him, and Kodachi Nagi and others often join in the fun for some reason, turning the club room that was originally the most suitable for reading into a noisy stage. The plot of this book revolves around the daily life of such a group of people, but at some specific critical moments, everyone will receive text messages in the name of the shepherd. Especially, when Kakei Kyoutarou was a child, he received a shepherd's bookmark with the number 77 1, which was a record of the shepherd's life. The story of becoming a shepherd began gradually.
