This is a drama that has been written by the same writer (oh my ghost and weightlifting fairy kim bok joo), so i gave it a try. It was quite funny and hilarious. Honestly, i enjoyed watching it. As usual, the writer will make the r/s growing in the drama that their characters also develop. I dislike the little sister coz she is a little nuts i think, female lead is too weak but i guess it is just her personality, but she is kind hearted. So for people who dislike weak female character, stay away from this drama. All in all, yeah, just put aside some logic and u will enjoy the show coz the humors are charming.
