Actually Amy, VV started with couples. They moved to a more party style with Petra, Ivo and Akira. It has slowly moved back to couples. It originally started with one house and two couples.
Like Zwavelaar said, they are people and they have no chemistry. If you have been a member of VV of any length. You know they make promises and they don't keep them.
Ivo was watching on his phone, His phone was visible on the livingroom cam.Then he showed Petra and they all started to watching on her laptop. All except Val.They were all giggling and laughing. Val tried to come over, they stopped him and Ivo started playing the game with him.
