Really great storyline overall, but unfortunately a lot of unnecessary crap in the middle, and some boring painful episodes to watch at some point (around the 20 something). The 2 ML are really good and I was impressed by their performance (especially the transformation of the Wolf). Shame the FL was a bit annoying at times and her character not very consistent (I partly blame it on the script).
Still enjoyed most of it, and unlike most dramas, the main plot works until the end (I personally liked the ending very much). Wish they could edit a few useless scenes out and make it slightly shorter: would be perfect.
