Aesthetically on high-level, questioning the most important points of human life and importance of verbal, mental, physical, social, emotional development and the inability of developing them all on the same level. There are so many factors that influence one's development.

The concept of the drama and the backstory were brilliant. A touching sad, heartwarming and brilliant drama all along. This drama challenges lots of things that we wrongfully take for granted in today's society.

High quality acting. Tang Jun Sang gives one of the best performance ever perfomed by a Korean actors. Supported by amazing Lee Je Hoon and Ji Jin Hee and there isn't one single actor in this drama who didn't do their job to absolute perfection which make this drama on it's another level.

Watch this one! It shoves a fist in the face of convention and mainstream society. Great drama that argues its point with elegance and entertainment.
