Don't watch if you don't like love triangles, confusing romance, or romance-driven stories. This drama indeed has all of the above. The majority of the plot is focused on the two male leads tugging at the woman between them, and everything is set up so that the annoying tug-of-war lasts as long as possible. It's not uninteresting, but these types of stories require a more romantic soul to enjoy them, I suppose. Somebody with a lot more patience, who can watch the female lead running from one man's arms into the embrace of the other, while both of the male leads proclaim to anybody who'd listen their desire to "protect her".
I watched it mainly to drool over Lee Soo Hyuk, but even that wasn't enough in the end.
