Anna Matsumoto, a hardworking saleswoman at a beloved apparel brand, has a deep-seated distrust of men after a childhood incident where a boy cruelly mocked her sense of fashion. Her dedication pays off when she earns a transfer to the company’s head office press department, a dream role surrounded by the clothes she loves. But her excitement is immediately dampened when she learns her new direct supervisor is Kaoru, a charismatic and notoriously flirtatious man known for calling everyone “cute” and for his reputation as a playboy. Despite his casual demeanor, Kaoru is highly competent at his job, a fact that only frustrates Anna further when she finds herself reluctantly relying on his expertise.

What begins as a combative workplace relationship slowly shifts as Kaoru shows a persistent, genuine interest in Anna, chipping away at her defenses. His carefree attitude hides a surprisingly earnest side, and Anna finds herself caught off guard by her own growing feelings. Their relationship evolves from bickering to a secret office romance, with Kaoru’s increasingly focused affection forcing Anna to confront her past trauma. As they navigate the complications of hiding their love from colleagues, their bond deepens, but external pressures soon arise.

The story’s notable arcs include the fallout when their relationship becomes public knowledge within the company, leading to Kaoru being transferred to a different department to avoid conflict of interest. This separation tests their commitment, and the arrival of a rival who also has designs on Kaoru introduces new tension. Through jealousy, misunderstandings, and the challenges of balancing personal and professional lives, Anna learns to trust and opens her heart fully. The narrative concludes with the couple overcoming these obstacles, solidifying their love in a happy ending that affirms their growth from adversaries to devoted partners.
