I don't mind haters the drama was overall successful. That's the answer to them.
I never watched any drama of these two leads. But I really fell in love with them. The emotion they put throughout the series was splendid. The story was great and fresh, not like the other dramas. Both male and female lead had a strong character and pride.
The drama was poetry.

And I liked the ending. Never cried so much watching the drama, the emotions overflowed so much in the last episodes.
