Typical Korean plot. Always will go according to what a standard k-drama should be. The hero will go in ups and downs situations but eventually will win at the end. All I can see is a male protagonist, Sae-ro-yi, who is posting a decent life, who has morals like being proud and all, and full of enthusiasm but actually is a selfish, conceited, egocentric, insensitive and a total jerk guy, (if you come to think of it) especially to Soo-ah, who gave her a promise but to be abandoned at the end. When she was indeed the one who waited a long time and dedicated her life in helping to achieve his original goals and truly cared for him. A so-so, mediocre series and definitely not one of the best K-drama I have watched. Somehow disappointed that I wasted my time finishing this show.
