First of all, the star cast of this drama is our Lee Min-hoo with Kim Go-eun and secondly it's a power-pack.
It will give you all sorts of humour to romantic scenes to emotional to things beyond Science and most important the whole set-up and the concept.
It'll leave you thinking what's gonna happen next.
Not to forget our other cast carried it excellent (specially Woo Do-hwan).
It's highly recommend to anyone fantasizing K-Dramas.
Wish they'll give us a second part of it.
