That’s why anyone finding out they were together would have caused an absolute scandal. Half an hour ago, they had run into each other at one of the endless parties for wealthy, famous young adults, all champagne and flashing lights and fake laughter. It should have been another tense, careful interaction, smiles forced, polite jabs thrown, but instead, it had ended with them pressed together in the back of Sirius’s limo.
