Okay, Here i go ! When i was going to start this many comments and reviews were so negative that i lost interest ! But despite all that i give it a try ! And it hit me like 'boom' ! First of all this drama concept is unique ! Characters are perfect on their role. And don't get distracted by those tags ! It also has some sad and tragic part as well ! In all i loved this drama As i said earlier it has a unique story line. It will definitely hook you up to the end ! Thrilling and exciting stories are always favorite for many. But Romance is much less on this Drama ! It's a hardcore MEDICAL drama with so many patients and surgeries ! You will witness the stress and workload of Medical Staffs ! Main Artists were perfect on their roles. Even side roles and supportive cast was very good ! Junior artists also played key roles in this drama ! Their acting was so realistic ! Music was average ! those OST was good ! I won't say much. Those who rewatch dramas can rewatch ! Personally i don't like to waste my time on rewatching !
