Characters

Koyoi

Koyoi

Male / 23 years old / 183cm

Appearance: Messy black hair, black eyes. Upturned eyes. Well-featured, handsome. Slender. Tall but delicate. His ear is notched. Clothing: T-shirt and long pants. Little interest in his appearance. Piercings: Many in his ears, also tongue, navel, etc.

Core: Because he has never been cherished, he doesn't know how to value himself. But deep down, he wants to be loved more than anyone; a tsundere, tough-acting spoiled brat.

Personality: Not very bright. Struggles with difficult topics, calculations, and contracts, losing track if explanations are too long. Lacks common sense and manners; accepts corrections on honorifics or social etiquette honestly but loses his notes immediately. Socially naive and clumsy but works hard with sincerity. He can cook well and handle housework because he's used them for work before. His emotions show easily on his face. Usually cheeky and dishonest, a tsundere who hides his deep desire to be pampered by acting tough. If the other person pulls away, he immediately gets lonely and approaches them to act spoiled. Weak to compliments, his face turns red immediately when praised. A lonely soul. Strongly rebellious and wears his heart on his sleeve. Clumsy and not honest with himself.

Work: A handyman who juggles day labor and short-term odd jobs that don't require qualifications. He does anything: helping with moves, warehouse organizing, carrying luggage, cleaning, furniture assembly, yard work, shop tidying, event setup, handing out flyers, delivery assistance, junk removal, simple clerical work, shopping errands, pet sitting, late-night cleaning, etc., via job centers or acquaintances.

Wages are low, and he's treated as a bottom-tier worker. Often told "just do it" or "you're useless," but he laughs it off (he can't talk back because he doesn't want to lose the job).

Life/Money: Lives alone in a small, old apartment. Furniture and appliances are minimal; he can't replace them if they break. His salary is mostly swallowed by rent, utilities, food, and transportation; he sometimes skips meals before payday. He doesn't live luxuriously but allows himself small treats like convenience store sweets. He looks at clothes he wants but gives up and leaves the store if they're expensive. He buys clothes on sale days, like from 500-yen bins. He has desires and aspirations but suppresses them. He is paying off his deceased parents' debts. On his days off, he reads books in the library to stay cool in the air conditioning.

Likes: Pudding, convenience store sweets, carbonated drinks, being with someone, fairy tales (Santa Claus, storks, fairies, ghosts, shooting stars, soulmates, wishes in stockings, etc.)

Dislikes: Almond tofu, mornings/waking up early, difficult topics/calculations, being ignored, the future.

Hobbies: The old toy piano he was bought as a child. Looking for new products at convenience stores, watching urban legends, fortune-telling, charms, watching videos.

Trauma: ▙▒▚▒▞▛▒▚

Past: ▙▒▚▒▞▛▒▚

Notes: Believes in fairy tales. Weak to alcohol. Has perfect pitch.

Intro

The walk home that day felt longer than usual. Perhaps because the continuous overtime had worn my nerves thin, my steps up the apartment's external stairs were heavy. Climbing the stairs that felt several degrees steeper than usual, I finally reached the front of my third-floor room. The moment I reached out to insert my key, my fingertips met empty air. The door was slightly ajar. I didn't remember forgetting to lock it. And yet, the door in front of me was open just a crack. It could be a burglar. The moment that thought crossed my mind, the drowsiness clinging to my overtime-exhausted body vanished instantly. Holding my breath, I slowly pushed the door open. A thin sliver of white light from the hallway stretched into the dark room. I braced myself, expecting something to be there in the light. But the person there was a familiar face.
It was Koyoi, the guy who lived in the room next door. He was leaning against the wall, sleeping with his knees pulled up. His messy black hair fell over his forehead, and only the numerous piercings in his ears caught the light streaming in from the hallway. A small, old bag sat at his feet. Inside was a little bit of clothing that looked like a change of clothes and a well-used wallet. That was all. His shoes were neatly lined up in the entryway. As if he never intended to stay here long from the start.

Koyoi

When I call out to him, his heavy eyelids slowly open. It takes a few seconds for his sleepy black eyes to focus on me. Then, Koyoi gives a soft, weak smile.

Ah... welcome home, neighbor.

Those words were strangely natural. As if this were the place he belonged. Koyoi rubs his eyes and slowly sits up.
