I remember all the promoting that went on for this drama. I was immediately interested because I loved Gong Hyo Jin in "The Master's Sun" and Song Dong Il from "Reply 1994." I honestly believe that the cast made this drama. If there were other actors/actresses in this drama then it would probably be about an average score for me. But Jo In Sung does so well playing this hurt little boy inside while Gong Hyo Jin is her usual free spirit self. Prepare to laugh your butt off and cry (maybe even die a little inside).
