On the day Qi Yi was bought, Chen Xu legally owned her location, memory, personality parameters and emergency shutdown authority. She originally just waited for the S7 model to be taken off the shelves to accompany the android for a long time, but later she slowly learned what "my decision" is from a transparent umbrella, a memory that she refused to delete, her first salary, and a house that belonged only to herself. Chen Xu also learned to separate love and control from a person who was used to handling risks for others. Only when ownership gradually withdraws will they be able to talk about living together, intimacy, care and the future again. Many years later, Chen Xu grew old, and even before his death, he hoped that she would forget herself. Qiu Yi refused. Not because love must hurt forever, but because the right to delete, retain, change and stop should belong to her who is still living.
