Chobits is one of the classic proofs wherein people believe that robots are indeed able to love. The manga series may be more mature than what is recommended for my age, which is twelve-- like the fact that Hideki is used to seeing Chi without clothes on, or that he wanted a persecon to be able to download internet porn, or maybe even the fact that he wanted a girlfriend to lose virginity. I may even say that I wasn't able to read the series fully, because I had to shield my innocent eyes during those "mature" scenes.
Apart from that fact, this story is really heartfelt, and from somewhere in the middle, I realized that it was impossible for it all to end perfectly--- EVERYBODY happily living forever after. At some point in the story, Hideki had no choice, he had to give Chi up, or give up what Chi held dear. It surely was a tough choice, but he made the better one, nonetheless, since, in the end, he chose to make Chi "the one just for him", and was able to start over. The artwork of CLAMP was breathtaking, and my first sight of Chi left me almost speechleess. She looked as pure as an angel, and she was stunningly beautiful. The plot may have been complicated, but CLAMP found a way to untie every knot.
I thought that in the end, Chi would turn into a human, like most happy-ending love stories go by. But in the end, she just forgot everything that had happened previous, and this is one of the reminders that everything in due course finds its next beginning.
