Beings from distant planets don human skin and become Hosts of an angst-novel System, playing the most vicious, least human characters in stories that torment the protagonist.
Angst-Novel System 095: "Treat the protagonist like your pet."
Hold them high above you, toy with them in the palm of your hand.
The nonhumans, who had only just learned to speak human, said on the surface, "Got it."
In private, they whispered to each other: What exactly is a pet?
They heard that the human world's internet was advanced and could answer any question, so the nonhumans turned to it to learn the essentials of keeping pets.
They had a sudden revelation: keeping a pet means pampering it.

The following blurbs haven't been finalized yet, but these three worlds will all be included. There will probably be seven worlds in total.
[The domineering rich-kid intern and his underground plaything of a superior]
The internet says that if you keep a cat, you should always have treats ready to feed it, prepare little toys to play with together, trim its claws when appropriate, and hold it close to give it a few kisses all over.
But he never came across anything about the abandoned-cat effect.
[The poor, aloof tutor and his wealthy student]
The internet says that keeping fish doesn't require much contact. You only need to change the water now and then, scatter some fish food, and have the occasional vague interaction through the glass.
But if the fish is very possessive, you'd better not let him know you keep other fish, too.
[The control-freak interstellar major general and his canary]
The internet says that canaries are fragile and need special care.
The interstellar major general combines theory and practice, mixing the bird's food himself and building its cage. Then, after hearing that canaries must be raised with clean water, he sets out on a scientific research path to purify pollution.
By the time he comes to his senses, his reputation has gone from pure-blooded pervert to lovesick savior of the world.
Theme: Kindness is the most beautiful foundation.
