CLAMP manages to write a beautiful love story contained within these eight volumes. There is absolutely no filler within these volumes, which was something that the anime adaptation had far too much of (especially in the first half). The romantic development between Hideki (the male protagonist) and Chi (his lady android love) is remarkable, and actually managed to move me (which rarely happens to me in almost every romance I've seen). Aside from the development between the two main protagonists, I also found myself genuinely moved by the interactions and relationships of the supporting cast. I also appreciated the somewhat philosophical bits dealing with love and technology.
(And also, Sumomo wasn't as unbearable in the manga as she was in the anime, and I think that alone is deserving of a full star.)
The artwork is also a merit of this manga. CLAMP doesn't overdo it with details, but also doesn't make their art too bland and lacking.
Some may be turned off by the fan-service (there isn't TOO much, but still some), but I would highly recommend reading all eight volumes regardless.
