Kouhei Somei stopped writing after the death of Yoshino, his writing friend. Haunted by her death, he lost his taste for life and gave up his dream of one day becoming an author. Unable to really turn the page, he even continues to send her messages, knowing however that they will remain unanswered.
But his life changes when Mashiro, the new student at the school, asks him questions about his relationship with Yoshino, and, against all logic, he receives an answer to one of his messages...
