I think that a nice AU would be: Ruby the chef and Sapphire the pianist.
Ruby, sixteen years old, started out as a waitress in a modest restaurant, though she has always loved cooking since young age. One day, arrived early at work and with the kitchen still empty, she took the opportunity and prepared some “Ravioli alle pere con fonduta di taleggio” (pear ravioli filling with taleggio cheese fondue) and before she could even explain the chef, also owner of the restaurant, he tasted a forkful of it and almost cried because of the goodnes of the dish.
Sapphire, at age five, touched the keyboard for the first time and never left it ever after. At the age of ten, she composed her first melody and her piano teacher stared at her agape when she played it during one of the daly lesson.
She embarked on many tours, performing her concert around the world with the public always calling for an encore.
The two girls, both twenty one, met for the first time when the owner of the new restaurant in which Ruby worked, arranged a special night with the partecipation of the famous pianist Sapphire.
They now own a three star Michelin restaurant in Beach City renowned in the whole state. Ruby prepares the best dishes that make everyone drool and Sapphire entertains and bewitch the clients with her hands flowing on the keyboard. The restaurant is called “Il Granato Viola” (The Purple Garnet).
Often, afret all the clients are gone and the restaurant is close, Sapphire gives Ruby a preview of her new piece and as a reward Ruby prepares for her a nice fresh lemon sorbet with a drop of Vodka in it.
And then, back at home, the real dessert… if you know what I mean (but I’m sure you dooo >:3)
