This is my third K-Drama(second which I watched completely). I don't like the plastic look of actresses so I picked this as the premise was original where a washed out 37 year old meets her past 17-year old self. The lead actress seemed less plastic and more real.
The story simply doesn't have much elements for that many episodes and I was disappointed that the time travel element was not explored further at all.
The lead actor is extremely good looking and lights up the screen every time he comes on. There is some extremely good acting by the 17-year old girl Re Lee, she got the balance of a confident yet narcissistic girl right on spot. I also liked Kim yun-mi who beautifully portrays her mixed feelings in every situation, her general soft character, this was a very likeable character. The biggest disappointment was the main actress who has this slow way of speaking and then pausing as if she is going to say something profound and speak something trite.
The show is quite motivating if you are feeling down so will recommend but "Secret Garden" still remains my favourite. Wish they had cast "Ha Ji-Won" for the main role, she would have taken it to a different level.
