I had high expectations, as most of the reviews were really enthusiastic. Besides I like most of the actors. Truth is this drama is very good. The scenery, the acting, the plot, the music, everything is very good. I have no idea why I still got bored. So much so that I managed to go to bed without problem, without trying to scrape even a second. I even managed to watch several other dramas between episode 10 and 14. Not once did I feel the urge to go back to this one. I only finished so I could add it to my list.
What in the world happened? I think too many twists and turns, and side stories, and no real development of the romance. The chemistry was bad if you ask me. Same girl in Bulgasal, OMG! I didn't like Bulgasal either, but whenever the leads were near each other, I couldn't stand still. Their chemistry was phenomenal. In this drama, it felt like the real love story was between Yeon and his brother. That was actually what kept me interested. A bit.
The last scene is mentionned nowhere in the comments. How come? It ruins everything. (assuming there was something to ruin) Because of it, the great love feels like a scam, Yeon comes off as deceptive and manipulative (several time throughout the story actually).
So. Everything was good, but apart from the bromance, it left no impression.
