"How did it come to this?" Kazuo, the protagonist, is an unremarkable single man in his forties. One day, he finds an advertisement for a housekeeping android and immediately purchases one. Kazuo thought he had ordered a beautiful girl maid robot. However, what arrived was a boy android instead. Frustrated by the android's incompetence, Kazuo treats it harshly. However, as they live together, they gradually build a connection and Kazuo confronts his own past. This is a story of friendship between one man and one android, set in the near future where androids have become widespread. Some readers may perceive it as BL, so I have added a boys' love tag. However, there should be no romantic elements.
