Lee Dong Wook knows how to act, and his co-protagonist too (lucky us). His character is quite fun and a bit anti-hero but at the same time the typical hero. About the script I can say: is not new, sorry. The romantic story is well-known as many others, but if you are a fan of this kind of scprits, or maybe a new watcher of korean dramas, then be my guest and enjoy.
The music is very good for the story theme =)
It has very interesting actors and characters that for me became more interesting than the leads romantic story.
Anyways, is good, but nothing new.
