Yoon Song Ah is a talented and driven marketer at a top cosmetics brand, where she shines in her role with ambition and a dream to one day launch her own line. Balancing professionalism with her personal aspirations, she has little time—or patience—for romantic distractions.

Enter Chae Hyun Seung, a charming and energetic junior colleague who develops feelings for Song Ah. With his sharp marketing skills and an easygoing charm, Hyun Seung quickly becomes indispensable on her team. But it’s not just business he’s interested in—he’s determined to win her heart.

The catch? Song Ah has a firm rule: no dating younger men. Despite his sincerity and persistence, she keeps Hyun Seung at arm’s length, unwilling to risk crossing the line between work and romance. But as they collaborate on high-stakes projects, sparks fly, and Song Ah begins to question her own rules.

Will Song Ah let go of her preconceptions and give love a chance? Or will she stay focused on her career, leaving Hyun Seung in the friend zone? This romance is a slow-burn journey about love, ambition, and learning to embrace the unexpected.
