The 1st Shop of Coffee Prince (2007)

Go Eun Chan is a young woman who supports her mother and sister. Her short hair, boyish clothes, and manner often lead to her being mistaken for a young man. Laboring under this false impression, wealthy Choi Han Kyul hires her to pretend to be his "gay lover," to scare away the blind dates his grandmother has set up. Later, Han Kyul is asked to prove himself by managing a rundown coffee shop. Eun Chan maintains her false male identity to become a "Coffee Prince" employee. The charade becomes increasingly difficult as she falls in love with her boss. Han Kyul is both surprised and confused by his romantic feelings towards the "boy."
