Drama Special Series Season 1: Dream of 400 Years (2011)

both have an old love story.
A fantastic melodrama about love transcending time and space

Both are about a past love in a different life - both about finding the "reincarnated" one in the present - both have similar things - like a tomb being found decades later... clothing, hair, letters ectra... I personally enjoyed 'Dream of 400 years' more - as there was much more to the story and the development and end were much better.

Both the stories are based on the concepts of rebirth and immortal love.

both are suspense thrillers against the backdrop of the joseon dynasty..(though dream of 400 years is partly set in the modern times)..Further the main theme is the quest of a woman..

Both are short and sweet drama specials dealing with past lives and immortal love
