Lee Ye-joo is a female college student who lives alone and has a secret. She has a special ability to go to the future beyond by walking through the ‘door’ right before she dies! One day, she crossed the door and arrived in the future a thousand years ago to avoid a natural disaster!
However, a thousand years later, the Earth is in a situation where humanity is almost destroyed. A dark world where animals talk and humans try to eat each other.
Worse, a handsome madman who has superpowers has started chasing her to kill her! He called her a ‘time traveler’ and attributed her to the cause of doom.
At the moment she tried to survive and find a way back, she lied that she didn’t know what a ‘time traveler’ was.
