The Chobits is playing with butterflies.

Chi reads a series of children’s picture books, A City with No People, about a character searching for the “person just for me,” which were written pseudonymously by Chitose Hibiya as a way of reconnecting Chi to her past self as Elda, and to spark her own search for love. At the end of the series, Hideki finally admits that he loves Chi, and is her special person.

As the series progresses, Chi begins to have visions of another persocom who is identical to herself, and eventually learns this is Freya, her twin, and that Chi was originally called Elda; after Freya fell in love with her father and creator and had her heart broken (she couldn’t muster the courage to admit her feelings in the anime), her memories were downloaded into Chi, before her system was wiped at her own request.

The Chobits series deals with issues and ideals of virginity, and sexual intercourse in that Chi is effectively incapable of sexual intercourse (in the manga and in the series), as attempting to do so would “reset” her, so she must therefore only entrust her body to someone who cares for her well-being as opposed to a purely sexual relationship.
