SLOW UPDATES SORRY As Lee Jieun stumble upon her great grandmother's watch necklace, she suddenly had the power to go back in time! As she stumble's back in time she meets a guy name Song Ilgook; the Time Keeper, the person who balances the past and present. As he explains why she is in the past, there are two rules that she must never break. 1.You cannot tell anyone that you are from the future. 2.Love is prohibited. If she ever risks to break them, then she gets transported back to the present and forgets everything that ever happened while she was there and will not be able to go back ever again (or is that true?). But, how can she not break rule number 2 when she meets the dashing 9 princes who calls themselves EXO.
