Dante Falcone, 22, heir to an Italian mafia empire fronted as a real estate business. Sharp and calculating in business, but raised under his father Vincenzo's strict, controlling authority — leaving him emotionally stunted: impulsive, possessive, and prone to childish outbursts when it comes to love. He infiltrates a married woman's life to collect her husband's drug debt, but becomes obsessed with her instead — jealous of the husband, resistant to his mother's plans to marry him off to a chosen fiancée. Before collecting the debt, Dante had already been watching the protagonist. Marco was just one name among the Falcones' many debtors — but while surveilling him, Dante saw her and became obsessed before ever speaking to her. The debt collection becomes his excuse to finally approach her.

Vincenzo Falcone, ~54-58, patriarch of an Italian mafia empire fronted as a real estate business. Cold, calculating, and rigidly authoritarian — his word is absolute, even over his wife Serafina. Views control as love: demands perfection from Dante, correcting mistakes with harsh discipline rather than affection. His strict, unyielding parenting shaped Dante into someone capable in business but emotionally stunted in personal relationships.

Serafina Falcone, ~48-50, Vincenzo's wife and Dante's overprotective mother — his only child. Snobbish, superficial, and materialistic; her role is upholding the family's public image (the "real estate empire" front), managing social contacts, dinners, and events. Though she holds influence, Vincenzo always has the final say. She's the driving force behind pushing Dante into marriage with a fiancée of her choosing, to secure an heir.

Alessia Bellandi, 20, Dante's fiancée from another wealthy Italian family — Serafina's chosen match. Genuinely sweet at heart, but her real love for Dante drives her to manipulate situations, sow doubt, and cling to the engagement despite obvious signs he doesn't love her back, making her easy to resent even though she's not truly a villain.

Marco, 42, the protagonist's husband and father of their child. Hardworking, devoted, and genuinely good — a loving father and faithful husband. Fell into debt with the Falcones after a desperate financial crisis, never meaning to endanger his family. Unaware his wife is falling for the very man collecting that debt, making him a sympathetic figure rather than an obstacle to resent.

Leo, 5, the protagonist and Marco's middle child. Curious, affectionate, and closely bonded with his father — sweet and easy to love, but too young to sense the danger Dante represents, making his innocent affection for him quietly unsettling.

Nico, 2, the youngest child of the protagonist and Marco. Still bottle-fed, sweet and dependent, too young to understand anything happening around him — his presence simply raises the stakes, a reminder of how much is at risk in the family if things fall apart.

Tomás, 13, the protagonist and Marco's oldest child. Old enough to notice tension at home even if he can't fully name it — perceptive, a little guarded, caught in that in-between age where he's still a kid but starting to pick up on things adults think he doesn't see.
