Overall, What's Wrong With Secretary Kim was an enjoyable show. At first I cringed because the CEO said that he has an impeccable aura however, after watching the entire series, he really does have a strong aura of success and confidence. The plot was unpredictable at times which gave the show a really nice spark. The writers managed to integrate mystery, comedy and romance into the show.
Personally, I prefer historical shows, like Empress Ki or Queen Seondoek however, I did enjoy watching What's Wrong With Secretary Kim. The cast is attractive and the plot is surprisingly good. I think that I binged watched this in about a week with a friend.
Overall, I would recommend this show to a friend... 8.5/10
