i love how natural Kim Raewon's acting is in this show. I liked him here even better. I love Shin Sekyung so i watched this twice. Their chemistry for me was great and natural.
The supporting cast is also great esp Seo Jihye.
The love story of the past and the present was deeply developed and presented. The love of the male lead chararcter to the female lead is always firm and constant. Unrealistic that makes u fantasize a real prince charming. I give 5 stars.
