I really like this Drama ... i Think every thing in this drama was so good , & we could see about Bodyguards life & all of risks in their life ... Music was so good in all of the scenes & actors was so good , Specially yoo chun is one of the best actor , before this Drama i thought maybe he is so good in Romance & Melodrama but now in this drama we could see different yoochun & he is really good in all of the genre... in all of the episodes we could watch something new & this was so interesting & thrilling .... i really like action genre & if you like action genre too , so you shouldn't lose 3Days :D
