"The story takes place in 2029 where androids serve humans in various positions, even replacing them in many menial jobs. China's policy of only one child per family has led to a critical shortage of marriageable women, so an engineer designs an advanced robot named Arisa. She is programmed to be a wife to a man and mother to adopted children, and she does not abide by the Isaac Asimov's Three Laws of Robotics. She is designed to protect her family, which includes herself. However, her creator dies and Arisa is sold to the Russian robotics firm CRONOS. Arisa accidentally kills a man at CRONOS who tried to use her as a sex robot, and she then flees. She encounters little Sonya and automatically bonds with her and Arisa makes herself the child's guardian."
