I caught my boyfriend cheating on our couch. Then my dad called and told me to put on a white dress and become my step-sister.* My name is Aria Cole. I work at a bookstore. I pay 70% of the rent for apartment 4B. This morning, I walked in with blueberry muffins and caught my boyfriend of three years, Jaden, on our Facebook Marketplace couch with my best friend Maya wearing MY "BOOKS BEFORE BOYS" t-shirt. His excuse? "You're boring." I threw the muffins at him and kicked him out. Then my phone rang. It was my dad. Panicked. My perfect step-sister Chloe — the one who was supposed to marry billionaire Mafia heir ALESSANDRO DE LUCA to save our family's company — just left a note and ran. And Alessandro De Luca is sitting in our living room right now. Dad's words: _"Put on any white dress and come home now. Pretend you are Chloe. Or he will take everything."_ I just lost a boyfriend who cheated on me. Now I have to marry a monster I have never met. And my socks still have spilled coffee on them.
