I won't lie. I'm kind of upset writing this review because I just finished the show, and the ending left me unsatisfied. It was a happy ending, but I expected so much more. There were questions unanswered, and some of the scenarios that happened in the show did not really get fixed. I also felt like some of the characters and their relationships should have been focused and delved into more. I do have to say that I loved the idea of this show (the whole night errand thing). All the main characters and their personalities were fun to watch. The action and fight scenes were exciting and fun. The actors did a phenomenal job and were the main reason I went back to keep watching. I only wish the storyline could have taken a better turn in the last half of the show. I still think everyone should check 'Healer' out because it's different from the typical K-dramas you see. It mixes action, comedy, drama, and romance, and it does a good job at it.
