In New York's old-money circles, Mia Hart and Noah Bennett are famously called the “useless couple”—she spends her brothers’black cards on desserts, he suffers from severe social anxiety and congenital heart disease, barely able to finish a sentence. That changes at the Sterling charity gala, where hostess Olivia publicly brands Mia a mistress, smashes her phone, seizes Noah's emergency medication, and drags him toward a strong magnetic display, nearly disabling his implanted defibrillator. But Olivia doesn't know that Mia's distress call has triggered the Hart family's emergency system. Within seconds, New York's two most untouchable families storm the hall. The truth emerges: the real mistress is Olivia's own hated half-sister. That night, everyone learns that behind the “useless couple” stand the city's fiercest protectors. Noah transforms from a fragile heir into a man who actively defends his wife, and together they make every perpetrator pay—while reclaiming their own future, on their own terms.
