This drama is worth watching.I have seen time travelling dramas but this one made me confused with my emotions.this drama made me cry a lot in just 4 episodes and I hope it has a happy ending.the old im sol and present im sol are completely opposite which makes the whole past messed up as she travels in the past and comes back again to present.this drama made me angry,happy,emotional at the same time.this is the best drama but you should have control on emotions cuz I went to bath,just to openly cry cuz their story made me really sad. Love it
