Definitely a masterpiece. It takes us to a roller coaster of emotions and leaves us with overwhelming feeling of self-reflection in the end. This drama made me cry in each episode but the last three episodes wounded me in a good way :) The acting was so on point and of course, Lee Je Hoon never disappoints but Tang Joon Sang was also good in this drama. If you want to ugly cry and release emotions, this is a must-watch.
