I can't lie, this series are extremely messed up. All of the characters are manipulative, kinda stubborn, really horny, also some of them have certain addictions, BUT!! I think you can learn a lot from the characters. They're all so interesting for analyzing and you can make so much theories and conspiracies about their behavior. It's not all sex, it covers a lot of social problems. And the cast is so strong, they all are perfect for their roles everyone is delivering his role in the best way possible. Go watch it if you wanna talk with people about social problems and analize people's behavior. And of course to support the amazing cast, they deserve it.
