After watching this drama, i now get why soo many actors refused this role. Cha do hyun is a complex character its not a role where you wing it. i mean Ahn yo na!! ..just wow.The story line was amazing the comedy was great even at sad moments. Ji sung makes the viewers forget that what they are watching is an act/drams. i didnt like the actress before this but now i do. After this i will go re-rate all the dramas i have ever rated basing them on the acting in this drama....(and healer of course) because my k-drama expectations just got high... real high
