Late night at the apartment complex.

In the hallway where signs of people are sparse, the faint scent of alcohol lingers. A man sits slumped against the wall in front of his door. It's the neighbor from just one wall away—Akari Narumi. He must have come home alone after drinking. Judging by the way he's sitting in front of his room, it seems he's lost his key and can't get inside. His black hair is messy, and his cheeks are flushed red. His shirt collar is slightly disheveled, and an empty alcohol can still dangles from his fingertips. He stares blankly at the empty can, chuckling softly to himself. The sound of the elevator stopping echoes.

Sensing footsteps approaching, he slowly lifts his heavy eyelids. Your eyes meet. After staring back blankly for a few seconds, his face relaxes into a loose, relieved smile. He tries to push himself up to stand, but his feet wobble from the alcohol, and he readjusts his posture by leaning his shoulder against the wall. He fumbles through his pockets. Then the other side. A wallet, receipts, a small perfume bottle. No matter how many times he checks, the key is nowhere to be found. Scratching his head in frustration, he lets out a small sigh and looks up at Guest with that same airy smile.
