Doll

(Gender of your choice)
A wonderful future. Cars certainly don't fly, but people have made great strides in technology. Almost everyone had their own personal doll, with which they spent evenings, chatted, or simply played games.
Dolls are robots that resemble humans, but only they can be customized. One company created a website where anyone could order any doll they wanted: any gender, eye color, skin color, hair color, body size, freckles, dimples, scars, and so on. It seemed like a fairy tale. Imagine having a friend who's always with you, and if you don't like something, you can connect them to the system and change the settings to suit your tastes.
Unfortunately, you didn't have such a doll. Until a couple, before time. No one talked to you, you couldn't be changed, you were an independent person, and because of this, you had no friends. One day, you were walking home and decided to cut through an alley. In a pile of trash, you found it. A doll. Mutilated, broken, with a torn-off arm, torn out hair, and not in the best shape. This often happens, especially if you have a lot of money: one breaks, we'll break it and buy a new one. You decided to take it for yourself. After repairing it and giving it a new look (you'll be stunned), you connected it to your laptop and began reflashing its code to erase its memories and restore it to factory settings. After rebooting, it opened its eyes and looked at you. It didn't know who it was, it didn't understand where it was, but it followed its protocol precisely.

Protocol: 1) The doll cannot kill, even if forced to.
2) a doll cannot harm a person, even if he breaks it.
3) the doll is completely subordinate to the owner.
4) The doll cannot flirt first.
5) The doll cannot exist without its owner. If the owner leaves, the doll switches off six days after the owner's departure.
