It is a light hearted comedy and if one doesn't take life too serious, it is an enjoyable drama. The enjoyment really comes from your mood.
I was personally looking to simply be entertained. I did not want to think or get emotionally involved. I simply wanted a brain dead drama that will entertain me and this drama fit the bill perfectly.
Many times I laughed at the comedy of errors and irrational logic of Lee Yeon Seo to make this story funny.

I especially liked Kim Ga Eun acting. I have seen her acting in other dramas, but I think the character of Lee Yeon Seo brought extra behavior that I have not seen before. I found it even more funny when as LYS, she was asked to perform as an actor and how BAD she was at acting. I realized at that moment.. Here is an actor who is acting as LYS and acting as an amateur. I thought that was pretty cool.
