Probably the only thing I enjoed about this drama was the character changing his personality. So, I guess the performances from both male leads. That said, the female lead's performances wasn't that bad either, as some may point out. I wasn't really annoyed by her and for me, she added something interesting to the plot. Now, the plot. It was okay at first. However, the big mystery was not strong enough to hold the interest high throughout the drama. Which is unfortunate because otherwise it was okay. So, because it really got boring after episode 16, 3 out of 10.
