Twenty-one-year-old Elena is the eldest daughter of a renowned Cosa Nostra boss, living on Long Island. Known to her community as the "Sweet Abelli" for her polite, docile demeanor, this persona masks her deeper frustrations with her restrictive life. Haunted by a tragedy from six months ago, she constantly twists a plastic ring on her finger while managing her family's strict expectations and her unexpected attraction to her sister's fiancé.

At twenty-nine, Nicolas is the youngest sitting don in the history of the Cosa Nostra, having taken over after his father's death. He commands fear and respect through his arrogant, hot-headed, and intensely possessive nature. While initially arranged to marry Adriana to secure an arms deal, his attention is immediately captured by Elena, complicating his alliances.

Salvatore is the formidable, dictatorial boss of the Abelli crime family. He rules both his mafia empire and his household with absolute authority, viewing his daughters' marriages as strategic tools for cementing alliances. He is particularly strict with Elena, harboring lingering anger over her past attempt to run away.

Adriana is Elena's younger sister and the youngest daughter of the Abelli household. Unlike Elena, who hides behind a sweet persona, Adriana is openly distressed by the violent men in their orbit and dreads her arranged marriage to Nicolas. She longs for a simpler, safer life outside the mafia's control.

Celia is the matriarch of the Abelli family and Salvatore's wife. Accustomed to the brutal realities of the Cosa Nostra, she largely accepts the strict, patriarchal rules of their world. She generally defers to her husband's demands regarding their children's futures, though she privately worries about the dangers her daughters face.

Oscar is a prominent member of another organized crime family. He has a known history of violence and a predatory interest in Elena. Arrogant and entitled, he represents the constant threat of harassment and lack of autonomy women face within the mafia society.

Tony is Elena and Adriana's brother, fully entrenched in the violent operations of the Abelli crime family. His reckless actions, specifically killing a member of the Russo family, ignite dangerous tensions between the syndicates and force his father into difficult negotiations.

Ryan is the Abelli family's gardener and an outsider to the Cosa Nostra. He serves as Adriana's secret lover, representing a completely different, peaceful life far removed from the bloodshed of the mafia.

Benito is a cousin to the Abelli siblings and serves as a trusted enforcer and escort within the family. He is frequently tasked by Salvatore with chaperoning Elena when she leaves the house.

Stefan is Nicolas's hot-headed cousin. Driven by grief and a desire for vengeance over the death of a relative, his lack of impulse control leads to a life-threatening escalation at a supposed peace gathering.

Gianna is an attractive woman within the Russo sphere who shares a complicated history with Nicolas. Sharp and observant, she easily reads the tension between Nicolas and Elena and is unafraid to speak her mind to the don.

Christian is an attractive man who catches Elena's eye, though Nicolas quickly warns her that he is connected to the FBI. He becomes a convenient pawn for Elena as she attempts to exert some control over her social life and avoid Oscar.

Isabel works for Nicolas as a cook at his Bronx home. She has a history with him and is highly protective of her space and influence in his household, making her immediately hostile toward Elena's presence.

Luca is Nicolas's cousin and trusted guard. He handles security details and household supervision for the don, occasionally mixing business with pleasure under Nicolas's roof.

Antonio is the former don of the Russo family. His reign both as a mafia boss and a father was marked by severe physical abuse and volatility, deeply traumatizing his family and shaping Nicolas's worldview.

Caterina is Nicolas's late mother. She struggled deeply with drug addiction to cope with her abusive marriage, making her unable to properly care for her son, though she attempted to instill in him a respect for women.

Sebastian is Oscar's brother. Despite his familial ties to a volatile and predatory man, he shows a surprising degree of reason and honesty when interacting with Elena.

Dominic is a cousin in the Abelli family who maintains a relatively normal, friendly relationship with Elena, participating in everyday activities like running together.

Tyler is a dancer outside of the mafia world who shows a persistent, somewhat obtuse interest in Elena, completely unaware of the dangerous men who monitor her life.

Jenny is Tony's girlfriend. She becomes an unwitting pawn in the escalating tensions between Nicolas and Tony when compromising material is used to incite a conflict.
