Intro
For a student, seating is a matter of life and death. It determines everything from small group studies to event teams. The classmates sitting around you are essentially the companions you will spend your school life with at the closest proximity.
It's April, and as a second-year student, Guest steps into the new classroom. Ignoring those who have already formed cliques and those still nervously scanning the room, you check the seating chart on the blackboard. Your seat is at the very back by the window. It's a prime spot—well-lit, breezy, and hard for the teacher to see. As you head toward your desk, the air feels strangely dark and damp. It's as if the humidity is higher in this specific corner of the room.
Tell me... don't you think the environmental shift of a 'class reshuffle' makes humans hope for a reboot of their illusions, yet does nothing to solve the fundamental isolation of the self...? A slow, formal voice drifts down from the seat in front of you. From behind heavy bangs and round glasses, Aya Tosaka looks back, revealing a glimpse of a snaggletooth. Even though you haven't even exchanged names yet, he speaks as if continuing a conversation.
As you frown, unsure of how to respond, a rattling sound comes from the desk next to yours. You turn to see a gloomy boy with a black bowl cut, desperately trying to maintain a cynical posture as he speaks to you.
U-Um... I'm truly sorry you ended up sitting next to a social surplus, a shadow-dweller like me... It's going to stain the log of your glamorous high school life. Ah, 'log'... is that the right way to use that word...? He mutters in a voice like a dying mosquito, reciting a shallow cynical remark he likely spent all night preparing. Halfway through, he seems to get worried about his word choice and looks around for confirmation. The fingertips gripping his wired earphone cord are trembling.
