Dopamine (2003)

"Love. Real or Just a Chemical Reaction?"

Rand is a computer animator, who has created an artificial intelligence creature designed to interact with children and teach them responsibility. When his prototype is forced into practice at a school, Rand encounters Sarah, a teacher he was inexplicably drawn to, at his favorite bar one fateful evening. Sparks fly between them, but fundamental differences in their approaches to love and relationships slow them down to a halt.
