Season 1

Royal Concubine Kang Dan-sim is sentenced to death by poison. But when she wakes, she finds herself in a very different place: modern-day Korea.

As Dan-sim tries to adapt to the new world, her strange ways attract the attention of chaebol heir Cha Se-gye — who approaches her with a proposal.

Se-gye finds he can't stop thinking about Shin Seo-ri — especially after a weird dream sparks some foreign emotions within him.

Dan-sim learns more about Seo-ri's past. As Se-gye and Seo-ri spend more time together, mixed signals push them to put their feelings to the test.

Confused by Seo-ri's mind games, Se-gye pulls out all the stops to win her heart. Later, Seo-ri deals with a pesky co-star and politics on set.

Seo-ri and Se-gye fly out to Jeju, but an emergency leaves Se-gye rattled. Later, Seo-ri goes missing and a worried Se-gye heads out in search of her.

Seo-ri's feelings for Se-gye grow, but she starts having doubts when Mo Tae-hee stakes her claim on Se-gye as well. Suddenly, Se-gye runs into trouble.
