Chi Bewildered
After Chii's reboot button is pushed, she escapes the 'peep show' room and is jumping around the city disabling all persocoms. She finally exhausts herself and Hideki catches her before she falls off a railing. Chii gets a job at a bakery having a five year anniversary thanks to Hideki. The manager offers Chii a permanent job - which she accepts only if Hideki allows it. She trys to give Hideki her payment but he refuses telling her that since she worked and earned it, it belongs to her and for her to buy her favorite things (whatever they may be).

Chobits
In the future, personal computers have developed into "Persocoms", mobile computers that look like human beings. Hideki Motosuwa, a prep school student, desperately wants to buy a Persocom but cannot afford to. One day he finds a Persocom that has been thrown away and decides to keep it. When he turns on the Persocom, all she can say is "Chii" so he decides to name her that. After a while it starts to become apparent that Chii is more than an average Persocom. Having much better performance, it seems that Chii might be a "Chobit", a type of advanced Persocom rumored to have independent thought.
