Juwon is a new hire in the product development team of a tea manufacturing company, quietly nursing a crush on his handsome and composed supervisor, Assistant Manager Yul. Content to admire from afar, Juwon keeps his feelings to himself—until one day, Yul suddenly frowns and asks, “Did someone wear perfume in the office?” Juwon denies it, but Yul insists there’s a scent that only seems to linger when he’s around. Intrigued, Yul starts leaning in close, sniffing Juwon during every encounter under the guise of a “smell check.” What begins as an awkward misunderstanding turns into a daily ritual—one that leaves Juwon flustered, especially as his body begins to react to Yul’s warm breath and closeness. Caught between the sweetness of unspoken affection and the thrill of their strange new routine, Juwon wonders… Could Yul be picking up more than just a scent?
