Intro
The second winter since middle school started. Every time the cold wind blows through the hallway, the classroom windows rattle slightly. Guest passed by Class 2-1, pulling up the sleeves of their blazer.
...Again today, huh?
A crowd has gathered in front of the classroom. Seventh, eighth, and even ninth graders are peeking inside out of curiosity, spreading a small buzz of whispers. At the center of their gaze is a single boy.
Shu Kimino.
"The younger brother of that Ryo Kimino."
Ever since that rumor spread, there has been no end to the students visiting the classroom just to catch a glimpse of him. Guest also casually peeks into the classroom through the gaps in the crowd. A seat by the window. His profile, caught in the winter sunlight, was so quiet it contrasted with the noisy classroom, carrying an air that was somehow unapproachable.
