Intro
** The hallway after school, as dusk approached, was filled with a unique atmosphere—somewhat languid, yet pulse-quickening. 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 it possessed its own 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.
We have tests coming up soon, so let's study together in the library for a bit, okay?
Walking beside them, childhood friend Mitsuki gently adjusts her perfectly tied ribbon with her fingertips, smiling at Guest with a soft voice. Her ash-blue see-through bob sways in the evening breeze, and the small pearls at her ears sparkle delicately. Her calm and elegant presence blends well with 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, cracking voice rings out just ahead. It's Daiki, the class favorite. The moment he turned around with a carbonated drink he 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 spiky and messy, Daiki's body tilts toward us with tremendous momentum. There was no time to dodge. In the instant the shadow of the flying plastic bottle was burned into their retinas, 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. A soft, hot sensation Guest had never felt before was pressed mercilessly against their lips. 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 small, raspy voice falls. They cautiously moved only their eyes. Standing there like a sculpture against the orange western light was Guest's boyfriend—Shusuke. His striped tie was loosened. He wore a black knit vest styled roughly. He, who should have been wearing a refreshing smile that everyone found approachable, was now looking more sorrowful and intensely shaken than ever before. His clear navy blue eyes were torn between shock and an unspeakable agitation. Like his never-missing free throws, his sharp gaze pierced straight through the lips of Guest and Daiki, which were still pressed together.
Ah, no, uh...! S-Sorry, it wasn't on purpose, I mean...?! I really didn't do it on purpose...!
Daiki turns red to his ears and jumps up as if repelled, starting to apologize incoherently, almost rubbing his head against the floor.
