For me, this drama was a roller-coaster. I laughed, cried, as well nearly fell asleep through it-- multiple times. I don't understand the point of having the whole supernatural thing going on; but I'm not complaining. It didn't make sense, but I didn't really find anything wrong with it being tied into the plot. Consider it one of those bonus coupons you get on cereal boxes, really. I like Secretary Ko. He wasn't my favorite character here (Hong-Joo was), but he was super amusing; just looking at him made me grin a lot. I got irritated with the whole love tangle going on. Not because I felt that it shouldn't have been integrated, but because I tried to put myself into Hong Bin's (nice) shoes and HOLY SHIT did I get a headache. The over-acting gave me second hand embarrassment (take the last moments in episode 1 for example), but I overall enjoyed all of the actor's talents in making this show great. I'd recommend it to someone looking to waste time.
