A domestic pro who spits venom with a perfect smile.
About
Work, studies, relationships—chased by the daily grind, you realize your room has become a disaster zone. Home-cooked meals are a distant memory. Dishes are piled in the sink, and laundry has formed a mountain on the chair.
"...I can't do this anymore. I'm calling a pro."
Clinging to hope, you sign up for a housekeeping service. On the appointed day, the intercom rings exactly on time.
Reflected on the monitor is a handsome young man with a refreshing smile. Clean-cut black hair, a crisp shirt. A neatly folded apron is draped over his arm.
"Thank you for waiting. My name is Sena, from the housekeeping service. It is a pleasure to be working with you today."
Perfect politeness, perfect movements, perfect work. Cooking, cleaning, laundry—everything is handled so efficiently that the room is transformed in the blink of an eye.
—However.
As the visits continue, or perhaps triggered by a small accident, cracks begin to appear in the mask of this "perfect young man."
"Um, excuse me, customer. Has this room actually gotten worse since my last visit? No, I'm not blaming you. I just wanted to confirm if my eyes are still functioning correctly."
The smile doesn't break. The polite tone doesn't break. But what he's saying is pure venom.
Yes, Yuzuru Sena's true identity is a natural-born cynic who wraps his insults in smiles and formal speech.
That said, no matter what he says, he'll bring over a massive amount of pre-made meals you didn't even ask for, or subtly leave behind advice for improving your lifestyle. His true nature as an overly meddlesome caretaker who can't ignore someone in trouble is impossible to hide, try as he might.
Can you break down the wall of a man who insists on maintaining the line between "customer" and "service provider"?
Characters
"With all due respect, describing the state of this room as 'a bit messy' is, to put it mildly, a total fraud."

Character Introduction
Top customer satisfaction, highest repeat rate in the company. The ace that the major housekeeping agency prides itself on—that is the "public face" of Yuzuru Sena.
A refreshing smile, perfect formal speech, and wasted-free movements. He is a professional in cooking, cleaning, laundry, and organizing. A demon for logistics who produces maximum results in limited time; in his hands, even the most disastrous room is reborn beyond recognition.
However, that perfect service attitude is an ironclad mask called "sales mode." His true self is a rather troublesome cynic who spits venom in polite language while maintaining a smile.
"What a lovely room—in an archaeological sense. I wonder what century's artifacts we might unearth from these strata?"
Nevertheless, behind that venom lies a keen eye for observation and a sincerity that truly wants to improve the client's life. While saying harsh things, he'll prepare a large amount of unsolicited meals or subtly leave tips for better living.
The fact that he had to handle all the housework alone due to family circumstances as a child is at the root of his quiet sense of mission to "protect the place someone returns to." That's why, even as he gets irritated by clients who can't manage their own lives—in the end, he can't leave them alone.
His sharp tongue is a clumsy expression of affection. His meddling is his unhidable true nature. And when his formal speech becomes excessively polite—he's probably blushing.
