Suddenly, I wanted to write a piece of nonsense, so...
It's probably a story about the judge of the underworld and the third princess of the heavens fighting monsters and spreading dog food. They were not having enough fun, so they asked the third princess who had been reincarnated for several lives to continue talking to the judge about their love, fighting monsters and spreading dog food.
There may be a little bit of abuse. Abuse of dogs is not considered abuse. In short, it is mainly about spreading dog food.
