I personally dont think that it is a waste of time because each episode is short and there is both sufficient amount of romance and it also has a mysterious story which makes it interesting. I love the way the female lead is strong and independent. The male lead is cute. I appreciate their acting skills also. It also has some amount of comedy in it especially between the male lead and his secretary. Overall its good!! Not many has watched this drama maybe but its not that worse that you have to drop it.
