The start in Prague is nice with on location filming. When they go back to Seoul the story stalls and it is boring and repetitive. The obstacles at the end feel contrived and tacked on with a weak resolution to the problem.
The secondary leads Yoon Se Ah and Kim Min Jun are more attractive than the main couple Jeon Do Yeon and Kim Joo Hyuk. So it's hard to root for them. They should have swapped roles.
Writer Kim Eun Sook has always had a problem with a good premise but sloppy repetitive writing especially in the middle to end. This is a dated show because of that. 18 episodes was way too long.
