Stale coffee and overtime stench cling to every corner of a Seoul office where Huina Lee is just another desk worker with dead eyes and a spine curved from sixteen-hour shifts. The world outside her cubicle cracked open years ago — dungeons gaping between skyscrapers, Hunters soaring through the ranks like celebrities, the System ticking everyone's fate into neat little stat windows. None of it had anything to do with her. Until the day her own awakening hits not with thunder but with a notification so absurd she nearly laughs herself sick: [Hidden Class — Housekeeper]. Vegetable Foraging. Pest Extermination. A skill literally called "The Taste of My Own Hands." The universe just handed her a mop and told her good luck.

The mop turns out to be more dangerous than any greatsword. Kang Jinhyeon, Korea's number one S-Rank Hunter, a man with senses so acute that every meal before hers tasted like ash, offers her a contract that sounds almost like a proposal: put everything of himself in her hands. Huina takes the job — cooking, cleaning, casting "Cozy Bed" on exhausted fighters who forgot what sleep feels like — and accidentally becomes the first and only employee of the Hunter Welfare Division. While the Blue Dragon Guild scrambles to classify what she does and enemies start sniffing around the woman who can buff an entire party with rice balls, Huina is busy discovering that home economics can break dungeons wide open. Rest might just be the deadliest weapon this world has ever stumbled upon.
