Can't say I enjoyed this one. You can tell what's going to happen pretty quickly. Most of the characters do the same stuff in each episode. Rowoon is the usual perfect dashing male with no flaws, no growth and no character development. He's the same from beginning to end. The rest is just 16 episodes of waiting for Yoon Song Ah to give in. Few of the other characters change or grow (with one very notable exception).

One side story is unconvincing, another is pretty depressing. Without giving away spoilers I could tell how everything was going to end pretty quickly and had to force myself to finish watching just for completion. This would have been better suited as a movie IMO.
