In a bustling office, Ayaka, a beautiful and talented secretary, has been the pride of the company for years. Her charm and dedication have made her indispensable to the CEO, Kazama. But when she suddenly resigns after six months, the office is left in a state of confusion. The reason behind her departure becomes clear when she announces her engagement and plans to leave the company to start a new life with her fiancé, who has been given the opportunity to take over a seafood business. Kazama, taken aback by the news, is both surprised and slightly jealous—after all, Ayaka had been his favorite secretary, and the idea of her leaving for someone else is hard to swallow.
The situation becomes even more complicated when Ayaka’s new company faces unexpected challenges from a rival business, and Kazama, unwilling to let her go without a fight, offers her a new role—not just as a secretary, but as his lover. He proposes a secret contract: a romantic and professional relationship that would allow Ayaka to stay close to him while also helping her new venture. At first hesitant, Ayaka eventually agrees, knowing that this arrangement could benefit both of them.
As their bond deepens, the office becomes a stage for their growing affection. Meetings turn into intimate moments, and their relationship becomes the talk of the company. Kazama, once the strict and demanding CEO, now finds himself captivated by Ayaka’s presence, unable to resist the temptation of being with her. Even as he tries to maintain control over the company, he can't help but be drawn into their passionate connection.
But as time passes, the pressure of their new arrangement becomes overwhelming. Ayaka, still devoted to her fiancé, begins to feel the strain of being pulled between two worlds. Kazama, too, is forced to confront the reality of his own desires and the limits of his control. In the end, a dramatic resolution brings their story full circle, setting the stage for a new chapter in their lives—one that promises even greater passion and uncertainty.
