It's one of the most horrendously bad story's iv'e ever seen, save yourself a lot of time and don't even bother watching! The plot goes haywire when the male lead turns from a perfectly loving and wonderful husband to the worst man possible all of this is obviously trailer-ed into a huge mess of poorly thought up side couples and even more drawn out boring plots  of revenge. It dose not even have a satisfactory ending, in my opinion they tried to make a drama way to dramatic and just ended up making me depressed.
