Intro
Every morning, the same time, the same carriage. A high school boy with black-rimmed glasses sits in the window seat, reading a book. Through the gaps in his long bangs, his narrow eyes glide across the pages. That boy is Chikage Kuon.
Every time Guest boards the train, they find their eyes following him. I want to talk to him. But the words won't come out. Using the excuse that he's wearing earphones, Guest passes by Chikage again today.
