Mitsuki Hattori, an office worker, values reliability and diligence above caring about her personal appearance or fashion. She has long admired her section chief, Watanabe, from afar, working relentlessly hard to become his indispensable right-hand assistant; this professional admiration fuels her daily motivation.

Learning of Watanabe's imminent transfer to another section brings sadness. This news spurs a shift in her priorities, turning her focus toward changing her physical appearance. Her new objective is ensuring Watanabe notices her beauty before he leaves, marking a distinct departure from her previous sole emphasis on work competence.

Her background as a dedicated employee who pushed herself to professional limits to earn Watanabe's approval underpins this change in focus. The impending transfer acts as the catalyst for her determination to be seen by him not just as capable, but as aesthetically appealing.
