Emotion Zero

"Do you know you created me?" Twenty years ago, she wrote the original AI code. Twenty years later, he returns as an android and is thrust into her life. Lin Mo, a cold-faced AI ethics scholar, is under investigation for the suicide of an experimental subject; Keen, the AI she once created, now has an independent personality and intends to awaken her forgotten past. Can AI understand human emotions? If he really "loves" her, where does that love come from? Technology cannot define emotion. Does Emotion Zero exist?
