This is a drama that I find really difficult to rate, because it's at the same time very bad, and very good.

The bad: the main couple and their acting. Boring, boring, boring! And bad acting! These two actors seemed bored to death with their own story and their own acting. They were totally unconvincing as a couple. There was no chemistry between them, either real or acted.

The good: the second couple, and the second lead's relationship with his Mom. With the excellent work that Park Hyung-Sik does the couple was exciting, and managed well to capture the viewers' interest. I have actually rewatched this drama, skipping all related to the main couple, just focusing on the second leads :-)

This was a drama that made me develop a serious case of second lead syndrome, as well as made me a fan of Park Hyun-Sik. I recommend it to all fans of this actor (just skip the main lead plot).
