I am sure that most of you "unsatisfied" with the ending say it because there wasn't a kiss at the end... the end stayed true to the drama and it felt natural and real, not sugar coated too much
some of you are hating on it too much... it's been five years, they both grew and are different people and learn from their past mistakes... when they truly loved each other, why not give themselves a second chance? it didn't feel unrealistic and if you don't get the symbolics in the last ep, that's on you...
