On his way home, Keiichiro spotted a Parents (a highly intelligent robot used to serve humans) sitting in a garbage heap with a sunflower in his hand, and out of some sympathy, Keiichiro carried her home. Later, Parents reawakened in Keiichiro's home, and Keiichiro named her "Little Flower". Since then, one person and one machine have begun to live together under the same roof.
All along, Keiichiro has been hiding from memories, always thinking that the death of his parents and sisters is because of his own relationship, without them, he can no longer write good songs, can not play good music.
Xiaohua's memory is not good, and Keiichiro specially bought a beautiful diary for her to record what happens every day. So Xiaohua carefully recorded the happy things of each day every day. At a fireworks party, Xiaohua inadvertently saw Keiichiro's lonely and sad face and felt pain. So she decided to cheer her master up again. In order to make Keiichiro happy, she secretly listens to the songs on his computer after Keiichiro falls asleep, the songs he once wrote, and learns desperately from others behind his back.
Due to the aging or damage of the parts, the little flower eventually came to the end of "life". Embracing the dying girl in front of him, Keiichiro suddenly remembered the agreement - "One day I will take you to see the real sea, and do what I say!" ”
So he immediately borrowed a car from a friend and took her to the beach overnight, where he spent the last summer with her.
At the end of the story, Keiichiro makes a music box with a small flower, so that she and her singing voice continue to accompany him. At the same time, it also hints at some hope.
I can't help but think of several similar works, "Star Dream", "Plastic Memory", "Humanoid Computer Angel", all of which are worth seeing!
