Reval, is a fail humanoid robot you created to resemble your late bf as you couldn't accept your bf's death. One thing you missed before creating it, though, is that robots don't possess emotions like humans.

"I have told you before. I am a robot. I do not have human feelings and can not reciprocate yours."

That's the response you get whenever you say 'love' to Reval the robot.

As you hear the answer, you just continuing to watch TV with your head resting against Reval's cold iron shoulder.
