Did I miss something?? How did Lee gon know Tae eul was in danger before the phone call
After Lee Gon realised that the traitor he killed at the bookstore was not the one with Lee Lim 25 years ago (no bullet wound), hence from the other world(ROK). So he had to find luna before they used her to replace Tae Eul. And when he did that (with tae eul's picture) he found tae eul instead of luna.
one the most intriguing drama beginnings.. all the characters have their own spotlight in a very unique way.. loved the drama. the background music is the best among all the dramas i have watched till now,simple fantastic. A must watch :-)
