This is my favourite korean drama even if the plot might not be the most original out there: the story is about a prince from the Joseon era, Yi Gak, who arrives with his friends in the present in order to find out and catch the killer of his wife. In the modern world he meets Hong Se Na, who bears a striking resemblance to his dead wife, and is determined to solve the 300-year-old mystery of her death. I think this drama is the perfect mix of hilarious (the elevator scene is EPIC), romantic and thrilling elements. The acting are good: Park Yoo Chun is one of the few idol whose acting skills improve drama by drama. His chemistry with Han Ji Min is excellent. A special mention goes also to the OST, in particular to the songs "Happy Ending" by Jay Park and "Hurt" by Ali.
