*SPOILER FREE* What I don't like from most of Korean dramas is that the plot usually drags. The characters are all hiding something and that caused misunderstanding and that muddied the water - frankly said, the characters were causing their own problems. That's why to avoid this annoying phase I tend to skip boring scenes or "hard to watch" scenes, and hope I can get to the ending faster because I wanted the characters to have a happy ending. Strangely, that didn't happen to me as I was watching this title. I didn't want it to end - I wanted it to be as long as possible. The pace in this drama is good, the connections are awesome and heartfelt, and most important: the plot doesn't drag. Though sadly, it ended abruptly (last two episodes felt rushed, and especially episode 16 felt as if the whole episode was a filler episode). Almost all of the important characters here grow for the better - with exceptions, of course. The ending could've been more elaborated, but it's all right the way it was. It's heartbreaking, and I really REALLY felt for the main character. He was such a tragic character with a tragic life. This has a fantastic directing - I think I really have to mention that. FANTASTIC directing - especially every scenes regarding Jae In and Gun Wook. The acting also really awesome, and Kim Nam Gil showed his 'prowess' so superbly - I felt like I would've fainted if I were to be treated such way by such an intimidating womanizer like Shim Gun Wook. His acting - and the writing & directing - made me, as a mere viewer - felt his irresistible charm and sex-appeal - even if all he did was kissing. His onscreen presence is MIND BLOWING. I've watched dozens and dozens of dramas and very rare actors/ instances can trigger those feelings and adoration from me. Now, people might find the ending... unsatisfying, to say the least. I kind of agree - but not because of the plot, but for the execution. It lack details, lack good pacing, felt rushed, and... you know, 'half-assed'. The way the last two episodes was carried almost felt like an insult to the first 15 episodes which were done BEAUTIFULLY. This drama should've gotten perfect mark from me, but the last two episodes took away one mark from me. So I gave it 90.
