Why are people mad at Axel/Cindy, when Ian/Cindy is a very different to maintain relationship, in which Ian constantly has to steer Cindy away from her selfishness and play the parent?
Axel/Cindy seems the most likely couple. Two spoiled, arrogant, self-absorbed divas who relish in each other and give each other what they want: Money, sex, excitement, luxury. Sure, Axel likely isn't faithful, controlling, and superficial, but isn't Cindy cut from the same cloth? I imagine she just accepts it and is content with the other advantages of being together with him. Probably simply cheating on him as well in her golden cage.
