The Relationship Between Robot Nanny and Owner Sublimates

Edgar was forced to buy the cheapest old-model nanny robot, feeling as heartbroken as if he had been robbed. He strictly stipulates that Ella is only allowed to use the minimum battery and can only move for four hours a day. However, when Ella accidentally spilled the coffee, Edgar flew into a rage, while Ella silently cleaned the floor and repaired the camera that he had treasured for many years. When Edgar fell ill and was bedridden, Ella took care of him day and night regardless of the power limit, and even repaired the heater with hidden parts. When he was about to sell off all his collections to upgrade Ella, Ella refused: "My core program has already set the home as my home."
