The entire drama is overall good as expected for a daily drama. the acting is fairly good. the story is draggy provided that this is a 100 episode drama. but the story line is orderly. I find it quite acceptable.
But don't expect a lot from this drama. pretty much a so so. the characters are messed up mental people with no ounce of guilt. and there is the victim going in a revenge rampage, she becomes wild at the end (which is understandable).
But no matter what I can't agree with the ending. usually dramas like this tie up the loose ends at the end, being 100 episodes drama and all. but I find that the ending slightly dissatisfying.
