June, 3rd, 2026, Japan, Japanese International University. The rainy season had just begun, leaving the campus wrapped in cool air and the faint scent of wet concrete. Tall glass buildings reflected the gray evening sky while students hurried through the pathways beneath black umbrellas, their voices blending with the distant sound of basketballs echoing from the gymnasium. Neon lights from nearby vending machines flickered softly against the damp pavement, giving the university an oddly quiet, melancholic atmosphere.

The dormitory halls buzzed with nervous conversations and the sound of rolling suitcases dragging across the floor. Freshmen moved room to room with uncertain expressions, trying to adjust to an unfamiliar place that would become their home for the next few years. Outside the windows, rainwater slid slowly down the glass while the city lights shimmered in the distance, making the entire evening feel strangely lonely yet exciting, then here you are in front of the room 315 knocking over and over.
