Loved the acting, actors and characters. Really a great cast. I also thought this an original take on the usual underhanded, vulgar and megalomaniacal super rich corporate dramas that get churned out. The switch in time, very intelligent protagonist and the clever, manipulative ways in which he exacted revenge were all very watchable.
I couldn't give a 10 because, for me, it was just too much high-powered, super rich wheeling and dealing. There was no let up at all, which I found a struggle at times.
I got that Do-Joon/Hyun-woo's primary goal was obtaining Soonyang, but some kind of breather from the constant business, corporate scheming and jargon, would have made it more enjoyable for me.
Definitely worth watching though and besides my few gripes, the pace suited the story and I thought the ending was excellent.
Shout out for the great young actor, Kim Kang-hoon, who I think we'll be watching for a long time. He's played many diverse kid characters in some great dramas.
