Azusa Kannawa, the ace of the publicity department, is renowned for her unmatched reliability. Her colleagues, however, find her no-nonsense demeanor intimidating. Unbeknownst to them, a socially awkward woman lies beneath this facade, simply struggling with casual communication and masking it with a strong attitude. However, her mask begins to crack when a promising rookie, Yuu Kamegawa, joins the team and Azusa is assigned as his mentor. Determined to guide Kamegawa just as her senior once trained her, Kannawa puts her utmost effort into showing him the ropes. But as they grow closer, she slowly lowers her guard, gradually revealing that the seemingly rigid department ace might actually be far kinder than anyone initially thought.
