Bette loves Mei, but Bette and Mei are on a break, so Bette can catch-up on the decade of dating experiences she missed before she came out.
So Bette is (reluctantly) on a dating odyssey: a quest to have lots of casual sex with lots of hot women and come back to Mei more experienced and more certain about what she wants. And now she has new friend Ruth as her dating guide, she can't possibly fail. It's just three months, then she'll be back with Mei.
It's the perfect plan … isn't it?
