He is a dog.
Although he has a human face, can speak human language, and can walk upright, he is just a dog, or in other words, he has officially become a... Dog since he was five years old.
The era is imaginary, neither women nor men are superior, men and women are equal, it is an era where men can have maids and women can have male servants.
It should be a short story, and it should... Not be a trap.
