The Serie as a whole is good on maybe 7 or 8 star.
But after spending a bunch of time with the story, and the characters, and the end is that bad, i wanted to throw my monitor out of window, it was so bad that i remain without word.
How can someone create a such good story and in the same time bury the whole piece under ground.

In generally, i am curious why are here so good reviews as 9-10 star. If this piece of work have this high pointing, what score these people than gave for example ( in my point of view ) to masterpiece as business proposal, Vincenzo, Descendats of the sun, whats wrong with secretary kim, crazy love, hapiness and more. according the outcome of scoring this drama, the mentioned by me should have score around 50 then.

I do not tell that the whole series is bad... but the ending of it is literally killing it.

More than overall 4.5 is overrated.
