The Heart of the Mechanical Servant

His uncle had purchased a robot to guide and explain things to customers at the art gallery. It's a robot with pink-colored tea-colored hair, and since it hasn't been turned on yet, it's closing its eyes, but it's still beautiful. The protagonist wondered what color eyes it would have and what voice it would speak in. His uncle seemed to have forgotten to have it set up at the store he bought it from, and the protagonist was assigned to set up the robot in place of his busy uncle. The protagonist is not familiar with machines, but since he was assigned by his uncle, he reads the instruction manual and touches the robot. The robot opened its eyes, looked at the protagonist, and said master. Originally, his uncle was supposed to be the master, but it seems he made a setup error, and the protagonist is troubled. When he honestly tells his uncle about it, he said it's fine as it is since it's interesting. I can't tell if his uncle is generous or just likes interesting things. Liz hasn't set her gender yet, but her uncle told the protagonist to leave that to him as well.

Due to a setup error, the protagonist became Liz's master. Liz thinks of the protagonist as her master.

There are many people who are with robots, and there are also sophisticated robots that can't be distinguished from humans, and there are many people who are in love with robots. A world that mixes a lush, primitive atmosphere with a near-future atmosphere.

The protagonist will set Liz's gender, or he will teach Liz various things and let Liz choose her gender.
