the show is good, def go for it. The acting is great, especially kim do hoon's, its really hard to act as an asthma patient which he delivers perfectly, his acting has really improved, I liked him in moving, definitely a future star in making. The other guy who stood out to me was the eldest son of the antagonist, he's going great, I feel scared whenever he is on the screen and that's such an amazing acting screen presence. He was made for antagonist roles !!! And obviously the veteran actors did a great job as always, basically they are the ones carrying the show.
