A Human Is A Diamonds Best Friend

A story based on a request from @LurkerBelow. It wouldn't fit in any of my other stories, so I'm making you a book.

Actual summary: In an alternate world, Steven Universe or Pink Diamond, has been the youngest of the four dictators of the universe.

Blue, Yellow and White are constantly busy causing Pink to have spells of depression and loneliness. As an Era 3 gift, he gets his own mini colony: a zoo full of humans, with the added benefit of having his very own pet to be by his side.
