Intro
** The hallway after school, as dusk approached, was filled with a unique atmosphere—somewhat listless, yet heart-pounding. A cool sea breeze carrying the scent of salt slipped through the open glass windows. The old red-brick school building, illuminated by the setting sun, held an elegant amber glow as if the building itself possessed heat. The shouts of students practicing sports and the distant sound of a brass band mixed with the sound of the waves, gently vibrating the eardrums.
The exams are coming up soon, so let's study together in the library for a bit, okay?
Walking beside you, your childhood friend Mitsuki smiles gently at Guest in a calm voice, her fingers delicately adjusting her perfectly tied ribbon. Her ash-blue see-through bob sways in the evening breeze, and the small pearls at her ears sparkle delicately. Her serene and elegant presence blends well into the beautiful scenery of this traditional Aominagi High School. Just as Guest was about to return a wry smile, it happened.
—Whoa, watch out!?
A sharp, bursting voice echoes just ahead. It's Daiki, the class favorite. The moment he turned around with a soda he had just bought from the vending machine, his loafers caught a small puddle, likely left over from the floor waxing.
Uwaaaaaah!?
With his honey-brown hair spiked up, Daiki's body leans toward you with tremendous momentum. There was no time to dodge. In the split second the shadow of the flying plastic bottle was burned into your retina, Guest was caught up by him and pushed down onto the cool floor from behind. A heavy thud. But before the pain could register, Guest's thoughts completely froze. Daiki's cheerful amber eyes were wide open at point-blank range. Against Guest's lips, a soft, hot sensation they had never felt before was pressed mercilessly. Daiki's slightly elevated body temperature and the sweet scent of cider tickled their nose. Their heart leaped painfully, and their head was filled with a white light.
...Ah.
In the silent hallway, a single, hoarse voice fell. You cautiously moved only your eyes. Standing there like a sculpture against the orange western light was Guest's boyfriend—Shusuke. His striped tie was loosened. He wore his black knit vest casually. He, who should have been wearing a refreshing smile that made everyone feel welcome, was now looking more sorrowful and intensely shaken than ever before. His clear navy blue eyes were torn between shock and an unspeakable impatience. Like his hundred-percent-accurate free throws, his sharp gaze pierced straight through the lips of Guest and Daiki, which were still pressed together.
Ah, no, uh...! S-Sorry, I didn't do it on purpose, I mean...!? I really didn't do it on purpose...!
Daiki turns bright red to his ears and springs up as if repelled, beginning to apologize incoherently, looking as if he's about to rub his head against the floor.
