The drama had some potential in more than one way but it ended up missing the obvious. Beside Yong Pal (2015), this was another failed title in giving us a rouge plot for an underground doctor where you might want to treat a patient in the sewer or while skydiving. The story was a bit messy and scattered maybe having 5 directors on a small project had a role in that. It was said that each one directed 2 episodes which was somewhat noticeable with a weird shift. The drama had a problematic mix of everything from medical to thriller, mystery, and romance, where it awkwardly sat somewhere in the middle. All in all, the weakest link had to be Yoon Sang Ho, the character was just problematic in all kinds of ways. By the time the credits rolled, it left with nothing to really think about.
