Synopsis
A man and a woman, despite hardly met before, they have been suffering the same dream and the same deja vu. A magnetic force leads them to Andong, the historic elegant city, and they find the anonymous woman’s 450 year-old letter in a museum. A fantastic melodrama about love transcending time and space.

This is a fantasy romance between Eun-gyo, who strangely felt a déjà vu in Andong, and In-woo, who felt an unknown sadness after he read a letter of a woman in 450 years-old grave.
