Liliadrop, renowned for exquisite women's cosmetics, boasts a staff of remarkable glamour and talent. Amidst this, Asako Yaeshima, known as 'Aseko' for her uncommon issue of excessive sweating, stands out. Determined to combat her dilemma, Asako concocts a unique routine using Liliadrop's soaps and deodorants to mask her scent. However, her efforts are not enough to deceive Koutarou Natori, a brilliant fragrance specialist with an exceptional sense of smell. Intrigued by the blend of Asako's natural aroma and the cosmetics, Koutarou proposes a peculiar solution: to sniff her daily for a week to craft new fragrances inspired by her. Driven by the company's reputation, Asako reluctantly agrees, unaware of the unexpected bond that would blossom between her and Koutarou.
