I haven't quite figured out the details yet. In a nutshell:
Your archenemy is your wife.
Spirit forms: Siberian tiger (female sentinel) x finless porpoise (male guide)
They have normal male and female anatomy, but, you know, there are toys, and the female lead also has a tiger tail
Xi Miao x Yu Zhu
"Cat" x "Fish" (yes, that's right. Even their spirit forms have to fit the archenemy setup.)
Theme: Cats and fish aren't limited to a predator-and-prey relationship
