However, her cuteness is all a lie—it is purely an act to achieve her self-centered goal of marrying a rich suitor.

However, Hime's facade cannot cover up her shortcomings at being a waitress, earning her the ire of one of her coworkers, Mitsuki Yano, the elegant "onee-sama" who often berates Hime over her mistakes. As Hime struggles to adjust to her new job in addition to Mitsuki's unrelenting hostility, her real personality begins seeping through the cracks.
