Karigari Hiroshi is a total robotics geek/genius who really likes this one girl, Marie. He's too shy to ask her out, so he becomes obsessed with creating a perfect android copy of Marie. He succeeds perfectly in creating Marie, an android with the intelligence and heart/emotions of a human and who looks just like Mari (though with different colored hair). Of course, Karigari never really considered the implications of such a thing...

From MangaHelpers:Miyama Akari is a poor high-school student with a part-time job, and she's tired of fitting in with all the girls who do their best to look and act the same. One girl in her class, Sendo Yuki, is different from the others. She rarely speaks or interacts with the other girls in the class, and Akari finds her intriguing. After she follows Yuki during lunch one day, Akari sees a whole other side of her, one that is fascinated with cameras and photography.As Akari and Yuki become friends, Akari can't ignore her growing attraction to Yuki. To make matters more confusing, a boy from their class, Rintaro, has started openly and persistently flirting with Akari. High school is a bewildering time for the heart, and Akari's is no exception... [tethysdust]
