A straight-forward romance unfolds as a new, younger employee relentlessly pursues his "perfect" team leader.

Yoo Seo-rin is the youngest team leader in the marketing department, a woman who is perfect in every way—from her skills and appearance to her personality. However, unlike her successful career in marketing, her love life doesn't go as planned.

After her fiancé breaks off their engagement, she vows never to date again. But she can't seem to get the new hire, Ha Kang-woo, out of her mind.

"I want to be the person you want me to be, whether as a team member or as a man."

Seo-rin tries to push him away when she finds out he is four years her junior. But Kang-woo, already captivated by her charm, begins his direct and unwavering pursuit.
