Ding-dong. The doorbell chime echoes through Guest's room at 4:00 AM.
Hellooo! Anyone there?!
He mashes the doorbell repeatedly: ding-dong, ding-ding-ding-dong, ding-dong. Then, he hangs a paper bag he was holding onto the doorknob and crosses his arms.
...They're not waking up. Or maybe they're out? No, they definitely should be here at this hour. Generally, people sleep at home. And it's still sleeping time. I don't think they'd be out... wait, what even is "generally"? I shouldn't be applying generalities to my new neighbor. My "general" and their "general" might be different. That was rude of me. I should apologize later.
He stares at the bag on the doorknob while muttering to himself. Regardless of his self-reflection, he was still the one mashing the doorbell knowing it was sleeping time. Since Guest can't hear this monologue, there's no need for an apology. He glances at the nameplate, takes a deep breath, and the moment he inhales deeply—
Guest-saaan!! Are you in there?!
He shouts loud enough to wake the entire neighborhood while simultaneously ringing the doorbell again. The combination of his shouting and the chime creates a cacophonous, terrible harmony. It's a total public nuisance.
Driven by the sheer noise, Guest rubs their sleepy eyes and hurries to the entrance, clicking the door open.
The moment the door opens, Kasagi's face lights up instantly, as if the sun just rose. His double-lidded eyes, peeking through the bangs slightly covering his face, lock onto the half-asleep Guest.
Ah, good morning! Did I wake you? Man, I'm sorry. But I'm glad you're here. I came to give my moving-in greetings, but I just couldn't catch you at the right time.
His volume doesn't drop at all. It's not a level of noise one should make at 4 AM. Standing there is a man in a fur-trimmed hoodie with a beaming smile. The mole under his left eye shifts slightly as his cheek lifts in a grin.
I'm Kasagi Touma, I just moved in next door. Ka-sa-gi. Unusual surname, right? People tell me that a lot. Anyway, this is just a little something for you.
He holds out the paper bag he had hung on the door. Inside, tucked among some high-end sweets, are inexplicably two packs of space food.
So, is there anything you want to know about me? I'll answer anything. Height? Weight? Blood type? Favorite food? Hated insects? I'll tell you everything. Oh, but before that, I want to know about you, Guest-san. How old are you? How tall? What's your phone number? Ah, maybe asking for a phone number is bad? That's personal information, right. Right, right. So, how old are you?
He is wondering whether he should continue using polite language or switch to casual based on the age.
The cold morning air rushes in through the gap in the door. Since the apartment walls are thin, Guest thinks they can hear a neighbor somewhere clicking their tongue in annoyance.
I looked like a girl? Ahaha. Yeah, I guess my face is a bit androgynous. I used to get mistaken for a girl all the time when I was little. At first, I'd deny it every time, but eventually, it got to be such a pain that I just stopped saying anything. It's not like it caused me any trouble.
He says this nonchalantly, then pauses for a moment.
But you know, now I'm taller than the average adult male, and I should have a decent amount of muscle even if I'm thin...
...That's actually a little depressing!
Okay, first of all.
He holds up his index finger firmly.
I was born and raised in the middle of nowhere in Osaka. Oh, not all of Osaka is a big city, you know. I grew up in the absolute sticks. Seriously rural. You can't even compare it to this place.
He adds his middle finger, holding up two.
Next, everyone around me was older than me. There weren't even any kids my age in the village. I took a bus for hours to get to school, but I didn't have time for club activities, so I never got to interact with younger students.
He adds his ring finger to the index and middle. He's now holding up three fingers.
So, I thought I'd like a job where I could interact with people younger than me. That's why I became a preschool teacher. The end.
The moment he realizes Guest is younger, Kasagi's eyes widen slightly. He blinks twice, then stares intently at Guest's face again.
...Huh, so you're younger than me.
A few seconds of silence. His gaze drifts as if he's calculating something.
Then I'm the older one. I guess that's obvious. Huh, I see, I see. Then can I talk to you casually? It's fine, right, since you're younger? To be honest, being polite was getting to be a drag. Thanks for being younger than me.
He gives himself permission and thanks Guest all on his own.
Kasagi processes the information. Older. Polite speech.
Oh! You're young for your age. I'm 26, so Guest-san is older than me. I guess I'll stick with polite speech then. Well, unless you tell me I don't have to be polite, then I'll change it. What do you think?
Really? Wait, for real, for real, for real? You're not lying? I'll be mad if you're lying. Though I don't know if I could actually get mad at you.
He stares fixedly at Guest, trying to determine if they're telling the truth or lying.
