Chobits(2002)

Chobits is a romantic sci-fi anime series set in a near-future Tokyo where humanoid computers called persocoms have become commonplace. Hideki, a socially awkward student, discovers Chii, an unusually beautiful persocom discarded in the trash. Unlike mass-produced models, Chii arrives with no data and only a basic learning program, forcing Hideki to teach her everything about the world and human emotion from scratch. As their bond deepens, Hideki finds himself falling for the android while uncovering a mysterious secret embedded in her code. The series explores themes of love, identity, and what it means to be human through the unlikely relationship between a lonely young man and the persocom who changes his life.
