From MangaHelpers:
The female cosmetics industry is naturally dominated by women, and Aura Cosmetics is no exception. The sales department consists exclusively of young, beautiful women, and it is the place where the few male employees in the company want to be. Unryu Toichiro is a recent graduate who unexpectedly gets placed into sales. He has a unique talent where his sense of smell becomes incredibly sensitive, as much as a dog, after he drinks alcohol. As he tries to learn the methods of becoming a great salesman, his co-workers slowly start to learn the secrets that Toichiro would rather keep hidden.
