[Strong female + house fighting + multiple male protagonists]
After being backstabbed by the person next to her, Gu Rou, the apocalyptic owl concubine, brought her space powers to an ancient era of true equality.
Here men and women have equal rights, and rights are the only foundation. As long as a man is strong enough, the princess can accept all the orders. As long as a woman is strong enough, there is nothing wrong with marrying a prince, prince, or even an emperor.
There are no brides-in-law here, only male wives.
What's so good about a peacock prince? The princess still has to share her man with others, so she might as well be more comfortable marrying a prince.
