Synopsis
With this story, I don't need anything else. If there is this novel "14 years old" and Tokico, the hero who surely lives in it ── But she appeared in front of me. A new school year homeroom that was supposed to be the beginning of every gray day. She who stood in front of the blackboard was "Tokiko" who should have been in the story I got. The distance between two people approaching clumsy. A strange entwined feeling between "Tokiko" in the story and "Tokiko Hiiragi" in front of me. The story of a reader and a hero who could not have met. What is at the end is ──.
