I saw the cast and I immediately started watching .. I was instantly hooked! the plot was really interesting and I couldn't stop watching but that only lasted for a few eps.. soon enough, it reverted to the usual drama you find in EVERY k-drama! it turned predictable and the ending(not sure I can even call it that) was a huuuge let down. Nonetheless, it was a good watch (most k-dramas don't have a good ending anyways :p ) ! the acting was really nice and it has some cool scenes. I'm not saying it's bad , it's just a bit disappointing compared to the trailer and the first few episodes. so if you're watching this , don't have any high hopes. It's still really enjoyable and somehow interesting.
