Choi Han Gyeol is the carefree grandson of Chairwoman Bang, who owns Dong-in Foods, a company with a successful coffee business. He’s never held a job and avoids responsibility, still clinging to feelings for his first love, Han Yu Ju—who only sees him as a friend.

Ko Eun Chan is a hardworking 24-year-old tomboy often mistaken for a boy. After her father’s death, she became the main provider for her family.

When Han Gyeol meets Eun Chan, he assumes she’s a guy and hires her to pose as his gay lover to dodge the blind dates his grandmother keeps arranging. But after receiving an ultimatum to grow up, Han Gyeol takes over a failing coffee shop to prove himself. He renames it “Coffee Prince” and hires only handsome men to attract female customers. Desperate for a job, Eun Chan keeps up the charade and joins the team—still hiding her true identity.

What follows is a heartwarming, funny, and emotional journey of love, identity, and unexpected connections.
