The engine roars roughly, cutting through the night air. The bike Guest is riding glides over the road, the wind piercing through the gaps in their clothes like a blade. Streetlights flash past, stretching their shadows long before swallowing them in an instant.

Cha Jiseon, riding on the back, has one hand loosely wrapped around Guest's waist. At first, it was just a touch to keep his balance, but as time passes, the pressure changes subtly. It feels less like he's holding on and more like he's feeling the body beneath.

The body heat radiating from Guest and the vibrations traveling up his back with every acceleration. Cha Jiseon tilts his head slightly, focusing on the sensation. Amidst the howling wind and the engine noise, Guest's breath feels strangely distinct.

At that moment, Cha Jiseon's hand moves slowly.

The hand that was holding the waist slides up, naturally reaching for the front of Guest's jacket. The hesitation is brief. His fingertips touch the zipper and pull it down lightly. The sound of the zipper opening is almost lost to the wind, but that single small movement changes the atmosphere entirely.

Cold air seeps into the opening, and at the same time, Cha Jiseon's hand slips inside.

Unlike the outside, it is warm inside the clothes. Cha Jiseon pauses for a moment, as if confirming that temperature.

Then, slowly, he slides his palm in.

Guest's body reacts minutely. The grip on the handlebars tightens, and the bike's speed wavers for a second before stabilizing again. No words are spoken, but the reaction alone says enough.

Feeling this, Cha Jiseon lets the corners of his mouth curl up slightly.

His hand doesn't go deeper. Instead, it lingers lightly inside. Not a brush against fabric, but direct skin-to-skin warmth. The heartbeat, felt more vividly because of the speed they're traveling.

Every time that pulse hits his fingertips, Cha Jiseon's fingers move ever so slowly.

It is too quiet to be a mere provocation, and too persistent to be a joke.

The wind continues to blow harshly and the road stretches endlessly ahead— But inside that narrow jacket, a completely different time is flowing.

Guest says nothing. Neither does Cha Jiseon.
