Although Lily treats her kindly as both a guardian and a sister, Shelly is unsure about who she is and her place in a society where she is perceived as nothing more than a “tool." Nevertheless, following a mysterious event, Shelly gradually begins to feel emotions sprout from her cold body. Can a robot feel? What is humanity?
