From the first episode I was on the edge of my seat until the very last 20 minutes. This drama was so unpredictable that it had me wondering what was going to happen next all the time. Every time I thought I had the ending figured out they threw in a little titbit that made me more confused than ever. Don't get me wrong it is not a jumble of random thoughts that was just stuck together with sticky tape to fill up the episodes. It's not that the story didn't make sense, it's just kept you guessing all the time.
And don't let the name Mistress fool you. There are two explicit scenes in the first two episodes, but nothing serious. But it is about what happens after an affair. The whole story was based around it. If I have to explain it I might give away a few spoilers.
The story revolves around four women and each one's story is interesting, adding to the mystery of the whole drama. You would think having 4 side stories would make the drama long and boring but each woman had a man in her life and it could be any of those men who was murdered in the end. And just as I thought it was this one or that one, they threw in a clue that completely threw me off again.
One thing I can say: don't mess with a bunch of women who are best friends! They stuck together until the very end.
It is one of those where you would like just one more episode. A season 2 would've been great.
