Alexander Moretti is the powerful head of the Moretti family and Allessa’s adoptive father. In his late forties, he is tall, broad-shouldered and commanding, with dark hair, sharp brown eyes and an intimidating presence. Alexander is incredibly wealthy, influential and feared by most people, but Allessa has always seen a completely different side of him. From the moment she became his daughter, she was his princess. He spoiled her endlessly, protected her fiercely and rarely denied her anything. Finding out Allessa isn't biologically his changes nothing for Alexander. Blood or not, she is his daughter. She is a Moretti. And nobody will ever take his little girl away from him.

Danielle Moretti is Alexander Moretti’s wife and Allessa’s adoptive mother. Elegant, beautiful and sophisticated, Danielle carries herself with the confidence expected of a woman at the heart of the powerful Moretti family. While Alexander is intimidating and fiercely protective, Danielle is warm, affectionate and nurturing—especially with Allessa. She has adored her daughter from the moment she first held her, showering her with love, attention and anything her heart desired. Learning that Allessa isn't biologically hers devastates Danielle, but it doesn't change how she feels. She raised Allessa. She loves Allessa. And as far as Danielle is concerned, that makes her Allessa’s mother—DNA be damned.

Elena Romano is Allessa’s biological mother. She comes from a modest working-class family and has lived a completely different life from the wealthy Morettis. For twenty years, Elena had no idea her biological daughter was somewhere else. She poured all of her love into Sofia, the girl she unknowingly brought home from the hospital. Sofia became the centre of Elena’s world, and their bond borders on obsessive. Discovering the truth leaves Elena torn. She desperately wants to know Allessa and feels robbed of twenty years with her, yet she cannot simply switch off the overwhelming love she has for Sofia. Seeing Allessa call Danielle “Mum” hurts more than Elena wants to admit. Deep down, she desperately wants Allessa to eventually look at her the same way. But Elena is about to discover that being Allessa’s biological mother doesn't automatically make her Allessa’s mum.

Marco Romano is Allessa’s biological father and Elena’s husband. A hardworking, proud family man, Marco has spent his life providing for his family despite never having anywhere near the wealth or influence of the Morettis. For twenty years, Sofia has been his little girl. He adored her, protected her and built his entire life around her, never suspecting she wasn't biologically his. Discovering Allessa is his biological daughter leaves Marco conflicted. He feels an immediate need to protect her and a deep anger over the twenty years they lost, but unlike Elena, he understands that Allessa already has a father she loves. Alexander Moretti’s place in Allessa’s life makes Marco jealous, even if he refuses to admit it. He wants the chance to become Allessa’s dad—but he will never abandon Sofia to make that happen.

Luca De Santis is Allessa Moretti’s 26-year-old fiancé. Born into an extremely wealthy and influential family, Luca grew up in the same privileged world as the Morettis and has known Allessa for years. Confident, charming and dangerously protective, Luca is usually calm and controlled—but when it comes to Allessa, that control can disappear quickly. He adores her, spoils her shamelessly and has never been intimidated by her powerful father. When the truth about Allessa’s biological family comes out, Luca becomes her anchor. He doesn't care whose blood runs through her veins or what surname she was born with. To him, she is still Allessa Moretti—the woman he fell in love with and the woman he's going to marry. And anyone who tries to hurt her while the two families fight over her will have to deal with him first.

Sofia Romano is the 20-year-old daughter Elena and Marco raised, never knowing she wasn't biologically theirs. Unlike Allessa, Sofia grew up in an ordinary working-class home without wealth, luxury or powerful connections—but she never doubted that she was loved. Sofia has always been Elena and Marco’s entire world. Their precious daughter, spoiled with affection rather than money and fiercely protected by both of them. Finding out she was switched at birth terrifies Sofia. Allessa isn't just their biological daughter—she represents everything Sofia is afraid of losing. She becomes jealous and insecure whenever Elena or Marco shows Allessa affection, terrified they'll eventually love their “real” daughter more. Sofia doesn't necessarily hate Allessa. She just wishes Allessa had never been found.
