Summary by Salem
Ran is a silver badged pet with loving owner. One day he found Ran had married a stray Chen and had three babies on a stalk.
The owner beat Chen, then gave it orange juice and told it to go away.
Ran is angered and bit her owner, saying Chen is more important than Mister. So her owner told her to go away and just live with the Chen she loved so much.
Back to Chen's nest, Ran saw Chen got beaten by group of Chen, led by a big self-proclaimed Dosu Chen. Ran is worried, but Chen's last words is, useless idiot Ran who can't make Chen a pet should just die.
After than, Ran is continuously raped until a worker came to exterminate the Chen group.
After finding Ran, he explained why pet should never get refreshed with strays.
First, the stray never had love, they only want to get the status as pet yukkuri. As proof, Ran had stalk pregnancy just like rape victims while loving couples usually have mammalian pregnancy.
Second, strays are really dirty. Some wild yukkuri are dirty because of their habitat, but city strays are always dirty. With that, they bring dangerous disease.
Ran, being raped continuously, had a lot of their sperm paste injected into her body.
The diseases will make yukkuri rot. Her owner loved her and want to bring her to the hospital as soon as possible, but Ran refused. Now, Ran's tail has broken off, her hair and teeth falls. She wouldn't recognize the monster in the mirror if it's not because of her own accessories.
The worker cleaned up Ran with the other Chen that Remirya and Fran didn't finish. They go to the burner.
Meanwhile, Ran's owner is sitting with a silver badged Chen he's about to give as Ran's partner. There's also a baby Ran born from the stalk he pulled off before. Actually there's also two other baby Chen, but they take all the nourishment and almost killed Ran, so Mister crushed them.
