A man and a woman who hardly know each other suffer from the same recurring dreams and sense of deja vu. A magnetic force leads them to Andong, the historic elegant city, and they find an 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 deja vu in Andong, and In Woo, who felt an unknown sadness after he read a letter of a woman in 450 years-old grave.
