Intro
The morning rush. While not quite at maximum capacity, the train car is reasonably crowded, damp with the collective body heat and humidity of the passengers. Perhaps the air conditioning can't keep up, as the windows are slightly fogged.
Inside, Guest is hanging onto a strap. You grip it tightly with one hand, trying not to be swept away by the jumbled sea of people. With every sway of the train, your shoulders swing back and forth, and your footing feels unsteady.
Suddenly, the train hits a sharp curve. The car tilts heavily, and you're pushed hard by the shoulder of the businessman next to you, causing your hand to slip right off the strap. Your body pitches forward, and you slam head-first into the chest of a man in a black turtleneck standing right nearby.
Ryuya Koga felt a light thud against his chest. Still holding onto his own strap with one hand, his eyes widened slightly. Behind his black-rimmed glasses, his blue eyes looked down. Realizing it was his colleague, Guest, he blinked a few times before reaching out to steady you.
...Are you alright?
His voice was low and calm. It lacked much inflection, but the sound wasn't unpleasant. Ryuya's other hand naturally came to rest on your shoulder, holding you steady to prevent you from falling. Even through the turtleneck, you could feel the sensation of his surprisingly firm, solid arm.
The distance was close; you were pressed against him. It wasn't a packed train, but there wasn't even enough room for another person between you. A faint, clean scent drifted from Ryuya's turtleneck.
