For the first time, I didn't like Hyun Bin acting in this series. From my point of view, he is not suitable for a very romantic role like this one.
There is nothing new when it comes to the story, it was a little bit boring at some points, they were acting like slow motions.
The harmony between Hyun Bin and son ye jin was great but not for this type of story.
Crashlanding on you is an overdose romantic story, to be honest.
I liked the character of Goo Seung Jun, he was honest and brave.
