After reading a few reviews on MDL, although skeptical, I decided to give it a go, and I was in for a nice surprise. Two main leads did their job really well and you can really feel the chemistry. Second male lead, was absolutely wonderful in every aspect, he is the guy any girl would be lucky to have, yet, I was rooting for Jeong (the main lead), the whole time, because Park Hae Jin did such a marvelous job portraying seemingly cold and distant, but a seriously sensitive and misunderstood character. Vulnerability he showed in front of Seol, really made me understand him as a carachter.
What I really loved about this drama is great understanding of characters and what motivates them. There were no unnecessary dramatic ploys, because drama can be found in everyday situations.
That being said, the finale was more than a disappointment and that's the reason that overall score is this low.
