Well I had this idea for a pairing:
- Young man/woman x robot servant: In 2025 Minneapolis, a young (wo)man inherits an antique store from a deceased relative. Among the belongings are the normal things - old books and toys, political memorabilia, various odds and ends... and one robotic servant. It was owned by the (wo)man's relative, and included in the will. However, it looks and behaves almost human. Before the relative died, they managed to install a special feature that allows the robot to become more and more human.
