Season 1

Han Kyul, the devil-may-care scion of a family of grocery story magnates, meets plucky tomboy Eun Chan, the hardworking breadwinner of her family.

Desperate to end the string of boring blind dates arranged by his family, Han Kyul hires Eun Chan, whom he thinks is a man, to pose as his boyfriend.

Eun Chan is having a miserable day when she bumps into Han Kyul, who reveals that his grandmother has bought him a dilapidated coffee shop to run.

Eun Chan is determined to fit in at Han Kyul's café, the Coffee Prince, for which he has hired male waiters, although her first day holds a surprise.

With business temporarily suspended at the café, Han Kyul and his staff go on a trip that turns out to be both stranger and more fun than anticipated.

Han Kyul's cousin Han Sung invites Eun Chan to an exhibit by his former girlfriend, artist Yoo Joo, and her unusual feminine dress impresses everyone.

Han Kyul spends more time with Eun Chan and is distressed to find himself developing unexpected feelings for the woman he still believes is a man.

When Chairwoman Hong is hospitalized, her devoted grandsons' visits to her lead to unexpected entanglements with Eun Chan and Yoo Joo.

Eun Chan confides in Yoo Joo that she has feelings for Han Kyul, and during a day together, Han Kyul is even more attracted to his "sworn brother".

Han Kyul is so confused by his feelings for Eun Chan that he acts coldly to her, and his actions provoke her to lash out until something big happens.

Eun Chan is hoping to reveal the truth to Han Kyul, but he has a surprise meeting that rattles him to the core, prompting him to want to run away.

Han Sung tries to help Han Kyul and Eun Chan reconcile after Eun Chan reveals her secret, but he also has to deal with his own romantic problems.

Han Kyul offers a solution to the problem of his upcoming move to New York and separation from Eun Chan, but more obstacles to happiness arise.

When Han Kyul tells his mother and grandmother that Eun Chan is a woman, they react badly, calling her a gold digger who's after the family's money.

When Han Kyul and Eun Chan accompany Yoo Joo on a fun day of wedding dress shopping, the festive clothes prompt Han Kyul to ask an important question.

Eun Chan's resolve to become independent before marrying makes Han Kyul question her love, and Chairwoman Hong interferes in their relationship.

It's Eun Chan's last day at the café before she leaves for Italy, and she and Han Kyul have two years of a long-distance relationship ahead of them.
