Firstly I didn't want to see this drama; I was sure it was something not boring but challenging, I don't know why but I had this thought. Then, a friend of mine said I should really see it. The plot: The plot is very interesting, apparently it seems simple, but it develops very gradually and always surprises you till the end. I have to say sometimes I got bored (there are 2 or 3 episodes I wished would end soon, but that's totally worth it.) The characters: I didn't love them all. The female lead is just a normal cute girl in love, who doesn't know well how cruel the world can be, but that shows to be strong episode after episode. I really liked her pure soul. The scheduler is my favourite character, and somehow to me is the male lead. When he is on screen you just can't think of anyone else. His cold, hot, cute, funny, helpful, caring personality is just essential in the show. The 'second' female lead (if we can say so, since she is more like the 'other' female lead)was just... ok, to me. I mean, I liked her very much, she was mature and very smart, but the thing in this drama is that every character rounds around the lead one. Because of that, even the male lead sounds just "ok", but that's not like unliking them: they are important, but the drama rounds around the things Ji Hyun discovers. The romance: Romance is something important to me. If there isn't romance I feel something is missing. I liked the romance they showed in this. It is not too much but well balanced. Actually I was expecting more, but it was not that bad. I reccomend this, it is a very good drama!
