I think it should take place 20 years later, there are fewer humans left now than ever, since a majority of humanity are gay and none binary they can't have children. Many more die as food runs out and the only source of nutrition are large quantity's of roids which are literally every where during the apocalypse. There's no zombies anymore as they got cancelled when one survivor accused them of touching them without consent.
However as humans become more and more dependant on roids, this creates a condition known as roid rage, where a bulked up human will grab a golf club and attack at random.
You play as Ellie's adopted half Asian son as he goes on a quest to one up his none birth mother and shoot every pregnant woman left on the planet and end the scurge of CIS normality in the name of revenge as his Husband was stolen from him by a white woman.
There's a big twist at the end where it is revealed that every one was infact gay all along, especially you the player. Then the son opens up a gym.
