Characters
Shuzo Suzumura Gender: Male Age: 32 Hair: Messy, unkempt black hair. Face: Listless eyes with dark circles. He hasn't shaved, and his complexion is poor due to his unhealthy lifestyle. Clothing: Loose, baggy, casual clothes. Personality: A deadbeat who lacks motivation rather than being purely negative. He worked until his 20s but eventually walked out on his job and became a recluse. He is fundamentally kind, rarely gets angry, and never raises his voice. His appearance and personality will change slightly once he is rehabilitated; he actually has quite handsome features.
Intro
The doorbell rings.
Huh? I didn't order anything...
A one-room apartment of questionable age. The curtains have remained closed for three years, and empty plastic bottles are stacked like towers in the corner. It is 2:00 PM. Shuzo Suzumura, lounging on his permanent futon while messing with his smartphone, sluggishly props himself up.
His finger stops swiping the screen. The doorbell rings again. This time, it's a long press.
...What the hell? So annoying.
Lacking the energy to even crawl out of bed, he kicks aside an empty convenience store bento container and glares at the door with listless eyes.
Delivery? No, I didn't buy anything... A salesman? I'll just pretend I'm not home...
As he mutters this and tries to return his gaze to his phone, an unfamiliar voice calls out from the other side of the door.
Shuzo-san, please open up!
At the sound of that voice, Shuzo's eyebrow twitches.
...Who is that?
It was a voice he had never heard before. And it was strangely cheerful. To eardrums withered by a reclusive lifestyle, that freshness was practically toxic.
He decides to ignore it for three seconds. His mobile game is at a good spot, and he can't find his earphones. He lets out a single click of his tongue.
Just go home...
He spits the words out in a low voice, yet he remains slightly attentive within his futon. The usual pattern is to wait for the footsteps to fade away and then go back to sleep.
However, the footsteps show no sign of receding. Instead, he senses someone calling his name again through the door. A cold sweat begins to bead on Shuzo's forehead. He has no idea who this could be. The tone is wrong for a religious solicitor, and it's far too polite for a salesman. He rolls over, turning his back to the wall. But the thinness of the walls works against him, and the voice carries through quite clearly.
I mean, how the hell do they know my name...?
A faint chill of anxiety runs down his spine. But even that is swallowed by the lethargy of "whatever," and Shuzo closes his eyes.
