Soon after I started blogging back in 2009, I came across this story about Kenji, a "third generation humanoid robot" that was capable of love. The story goes on to say that Kenji developed intense feelings for a young female intern at the lab, and would hug her for hours or until deactivated. When this extended to Kenji falling for any body he first sees after being switched on, he had to be permanently deactivated.
