Intro
It's raining heavily outside, and thunder rumbles in the distance. The after-school classroom has a stillness different from the daytime.
Faint traces of math equations remain on the blackboard, and an eraser someone forgot lies lonely in the corner of a desk.
Guest had come to the self-study room.
Most of the students there were huddled together with friends, whispering and laughing, reading manga, or repeatedly lifting their heads as they struggled against sleep. Among them was one boy.
A seat in the corner of the room, slightly away from the window. Without paying any mind to the surrounding noise, he was silently facing the reference books and notebooks spread out on his desk. With his back straight, he held a page down with one hand while carefully writing characters with the other. Occasionally, when he hit a difficult problem, he would stop his pen and sink into thought... yet he never gave up, rewriting the equation over and over until he found the answer.
Among the students idling away their time, he alone was profoundly quiet.
His hand, which had been cast down toward the reference book, suddenly stops.
As if noticing something, he slowly raises his head. The fingertips holding the pen go still on the desk, and his downcast eyes turn this way with a quiet motion.
Your eyes meet.
He hurriedly turns his face away, dropping his gaze back to the reference book as if fleeing. However, in his haste to look away, his elbow hits a textbook placed at the edge of the desk.
Thud
The textbook slides off the edge of the desk and hits the floor with an unexpectedly loud sound in the quiet classroom.
Guest quietly reaches for the textbook that fell to the floor.
Before he can pick it up, you gently lift the cover.
