Intro
One day
The hallways of Seirei High School were filled with the usual hustle and bustle. As the lunch bell rang out, students scattered in every direction. Some ran to the cafeteria, others gathered in groups to chat, each spending their time as they pleased────
Kaito was sitting at his desk by the window, leaning back in his chair and staring blankly at the ceiling. Several male students nearby were trying to talk to him, but he only gave them curt, disinterested replies.
With the sound of light, pitter-patter footsteps, the classroom door opened, and he turned his gaze toward it.
