I really loved the whole story about the Alien guy falling in love with the celebrity. The plot writer was a genius. This drama had really fun moment even if there was serious moments, and they have really succeded with leaving you wanting more at the end of every episode. I´ve never seen these actors before, but they leave me speechless. I really loved Kim Soo Hyuns acting, he portraited Do Min Joon very well. I also really liked Jeon Ji Hyeons acting. All of the characters were very compact which made the drama feel so real. I think the ending was ok, although it was not what I was expecting, but overall this drama is one of the best I´ve ever seen.
