At the office, a young male employee constantly gets scolded by his strict and capable superior, Miyahara Ichika. She is known around the workplace as a no-nonsense, intimidating boss. One evening, looking for a break from the pressure, he heads to a club and spots a stunning, stylish gyaru with an incredible body. When he gets a closer look, he realizes with shock that the playful, attractive woman is none other than his boss Miyahara. Seeing her outside of work changes everything, and he decides to take a risk, approaching her for a one-night stand by pointing out that he now knows her secret. Complicating matters is the discovery that Miyahara used to be a gyaru before she fully committed to her professional image.

As they begin a secret relationship behind the professional front they maintain at the office, both struggle to navigate the tension between their strict superior-subordinate dynamic and the more intimate, honest connection that develops outside of work. The story follows the push and pull of their relationship, driven by the contrast between Miyahara's stern facade at work and her relaxed, alluring side in private. In the second volume, a company trip adds further complications as both become more aware of each other's feelings but struggle to be honest. Their awkwardness is compounded by the appearance of a female colleague, Kanda Yume, who openly shows interest in the male protagonist, sparking jealousy and leading to a series of misunderstandings and intensified chemistry between the two leads.
