The protagonist himself is a fat man, and the writer, I, am also a fat man.

As a fat person, he is often teased by everyone because of his figure, and at the same time, because it is difficult for obese people to change the status quo, they have to adjust their mentality and be willing to accept this situation.

The title of the book is Fat Devil, one is because of the original body problem, and the other is also the reason for a demonic character. He is a human being, so there will be a person's personality, and because of the image of the demon in his heart, he will have psychological distortion. Therefore, the protagonist cannot simply be positioned as a fat man, he also has a non-human way of thinking and acting style. At present, I position him as a mixed man, so many things we can't just look at his behavior from the perspective of people, nor can we measure it by interests, we can't say that if someone is good to him, he will be good to that person, this is people's morality and psychology.

If you look at the behavior of the fat demon from the perspective of the demon in your heart, it should be very much in line with its requirements for the demon.

As for the direction of the plot, just like the title of the book, the plot is about the process of killing people and the psychological transformation, from a person who thinks that killing is wrong to a person who kills is right.

Therefore, readers are invited to calm down and feel the process of turning from human to demonic.
