One day, I – a high schooler – found a paperback in the hospital. The “Disease Coexistence Journal” was its title. It was a diary that my classmate, Sakura Yamauchi, had written in secret. Inside, it was written that due to her pancreatic disease, her days were numbered. And thus, I coincidentally went from Just-a-Classmate to a Secret-Knowing-Classmate. It was as if I were being drawn to her, who was my polar opposite. However, the world presented the girl that was already suffering from an illness with an equally cruel reality.

The girl’s name is Watarase Mamizu. After learning that she doesn’t have long to live, and there are things that she wants to do before she dies… “Will you let me help you with that?” “Really?” As this promise was made, the time that had frozen for me began moving again. *Grand Prize winner of the 23th Dengeki Novel Prize.*

People have “points”. Everyone’s lives are ruled by values or points based on various factors – looks, studying ability, and communication ability. Figures were floating above people’s heads. For some reason, I kept seeing said/such points. For example, the figure hovering over the head of my classmate, Yui Kasuga, is 46. Considerably low points. She doesn’t know how to read the mood and doesn’t even have friends. In order to raise Kasuga’s points, I end up getting involved with her–… Kasuga’s rising points, and I who was supposed to have given up all hope on changing. This is the story of our “branching point” in life.
