Keiichiro, a young man who lives alone in his house, went through a lot of pain in his life, since the tragic car accident that killed his parents and younger sister, blaming himself for surviving.One rainy day, he seeks shelter in an old shrine. There he notices a little girl, sitting on a chair, surrounded by garbage. She herself is garbage — an abandoned android dumped here by someone, holding a sunflower in her hands. Stricken by sudden sadness, he takes her with him to an android repair shop, where he is told that she will never function. So returning home, he dumps her in the dirty bathroom. Waking up the next morning, though, Keiichiro finds the little android girl standing in the kitchen, preparing breakfast. Still without a name — remembering the sunflower — Keiichiro names her Flower. And so begins the life for these two unlikely protagonists.
