There's a saying that goes "History is a constant communication of present and the past."

Everyday oc receives a flashback of what has happened in her past life.

She just pushes it off as a dream when one day she finds her heart aching in front of a man she has never met before. 

Then she finds herself rescuing few peculiar people out of the blue.

Then her story starts.

A timetravelling fusion love fusion of the joseon dynasty and contemporary society.
