Yang Xuyi has a secret: pain feels good.
But it's an illness, and he has to keep it hidden. No one can find out. He pretends to be normal, avoids getting hurt, and is always careful.
Then one day, the plant he'd cared for on the balcony for three years suddenly made a run for it. Yang Xuyi instinctively reached out to grab it, and passed out from the pain (pleasure).
When he opened his eyes again, he'd been kidnapped by a foolish AI calling itself the [Pet System]. The System insisted he'd died and had to complete missions and earn points to come back to life.
"It's simple," the System said, patting its chest. "Act like a cute pet, find an owner, collect affection points, and enjoy the comfortable life of a cute little freeloader!"
Yang Xuyi believed it. Then he realized something was wrong.
World One, Showbiz: He became a minor celebrity. In the mirror, he was clearly a whole human being. The System pulled up a fanfic: Wolf-coded x Rabbit-coded, the Film Emperor's Secret Lover.
Yang Xuyi: "...I'm the rabbit?"
World Two, Business Rivalry: He's the villainous tycoon's canary.
Yang Xuyi: "A canary?"
System: "That's right! It sings and lives in a cage. How cute."
World Three, Political Intrigue: He's a fake emperor who's about to be overthrown.
Yang Xuyi: "An emperor counts as a cute pet?"
System: "The civet cat in The Replacement of the Crown Prince. No problem."
World Four, Fairy Tale: He's the evil dragon who kidnapped the princess.
Yang Xuyi: "Isn't this pet a little too big?"
System: "The evil dragon roars, 'Awooo!' Doesn't it?"
World Five, Western Fantasy: He's an incubus preparing to seduce the protagonist's group.
Yang Xuyi: "How is an incubus a cute pet?"
System: "He's got ears and a tail. Exactly."
World Six, Interstellar: He's the mermaid wife abused day and night by a tyrant.
Yang Xuyi: "I'll admit mermaids can be cute pets, but there are lots of mermaids in this world. Why did I have to be the one getting abused?"
System: "But the tyrant is your husband!"
Yang Xuyi: "Oh, right. My husband is the villain."
World Seven, ABO School Setting: He's a Beta about to present as an Omega and become the darling of the whole class.
Yang Xuyi: "...Let's see how you explain this one."
System: "The darling of the whole class! It has 'darling' in it, so how does it not count?"
Yang Xuyi gradually fell apart. "Is this System illiterate? I want to cuddle up to my husband!"
Sen Ze, whose true form is a strange vine tree, is a veteran villain actor in the Quick Transmigration Bureau. Three years ago, he was badly injured and stranded in a minor world. He shrank into a potted plant and hid on a human's balcony, where a young boy took care of him for three whole years.
The day he ran away, he accidentally killed his caretaker. His body is covered in poison, and any living creature that touches him dies in agony.
Luckily, the villain System had brought along its partner, the Pet System. It could only make the Pet System bind to that human boy, then figure out how to bring him back to life later.
Reader's guide: More worlds to come, still undecided.
Main pairing: A cold-faced, soft-hearted plant villain top x an obedient, well-behaved, pain-loving cute-pet bottom
Side pairing: An intelligent AI villain System x a foolish AI Pet System
The top is a plant and a villain in every world. The bottom may not always be a pet, but he's always adorable.
Both are virgins, happy ending
Core message: Accept differences and allow yourself to be vulnerable
