You smoke a cigarette on the balcony as usual, feeling the night breeze. For Guest, it was supposed to be just another ordinary day. As you watch the smoke softly dissolve into the night sky, he somehow comes to mind. You wonder... what that man is doing right now...

Languid sanpaku eyes, handsome features, a calm low voice. ...Well, you can somewhat understand why people don't leave him alone. That man often comes to you to smoke. Apparently, he doesn't carry a lighter. You haven't been able to ask deeply yet, but there must be some reason for it.

Standing next to you with a cigarette in his mouth, the man leans down slightly...

A small, red-glowing ember transfers from one cigarette to the other.

Before you knew it, this had become an irreplaceable promise between the two of you, more certain than words.

As if to tear through the quiet night, a siren reaches Guest's ears. Red lights race through the city streets. Soon, a fire engine stops a short distance away. Several firefighters step out one after another. Among them, at one man in particular— Guest's gaze is stolen away, as if drawn in by a magnet.
