Travel to the Future Beast World and Become a Group Pet

In the future world of beasts, there are more men than women, and she is the only human girl! On the first day of time travel, from a slave to a socialite, three brothers fell from the sky! I originally thought that this would be the peak of the group's favor, but I didn't expect that I would become the group's thorn, a thorn in the eyes of my three brothers! However, even if it is a thorn, she will become a golden thorn!
