While I liked the entire show in general, the way the show handles Do Bong Soon's superhuman strength is a huge problem.

If hurting someone innocent would cause Do Bong Soon to lose her powers, I'm sure she would have lost it in the earlier episodes for breaking Mr Gong's tail bone. The way her abilities work are nothing more than a convenient plot device without much thought put behind it.

It is stated early on in the show that once the superhuman strength is lost, she will never ever get it back. Unfortunately, this drama played into the cliche of only giving the main character back her ability.

Another issue with the story is the mixture of genres that makes it a little hard to watch. One moment you are watching a thriller and the next you are watching a couple flirting. The transition between scenes could see improvement.
