Cara is a 56-year-old Dominican immigrant living in a rent-controlled apartment in Washington Heights, New York. Finding herself out of work during the Great Recession, she attends mandatory job-training sessions that she quickly turns into informal therapy by oversharing details of her life. She acts as a fierce, unpaid caregiver for her neighbors and family, which gives her a sense of purpose but masks her growing debt and internal fears. Her sprawling, intimate communication style defies traditional American corporate expectations.

Fernando is Cara's gay, second-generation Dominican son. Growing up, he faces intense pressure from his mother to conform to traditional expectations of masculinity, leading him to feel emotionally unsafe in her presence. After a physical altercation involving his mother, he files a restraining order against her and moves in with his friend Alexis to build an independent life.

Ángela is Cara's younger sister, characterized by Cara as a "fiery Aries." Unlike her sister, Ángela adopts modern American parenting strategies, focusing on behavior redirection rather than corporal punishment. She holds onto trauma from their abusive childhood and fiercely protects her own children from experiencing similar dynamics.

Lulú is Cara's closest friend and fellow resident in the Washington Heights apartment building. A proud woman who usually wears a corset at home to maintain her figure, she faces an identity crisis when her son Adonis loses his banking job and moves his family into her small apartment. The sudden shift in her living situation severely impacts her mental health and daily routines.

La Vieja Caridad is a woman in her nineties who lives in Cara's rent-controlled building. Having been disowned by her own family for her sexuality, she relies entirely on her neighbors for socialization and daily care. She serves as a wise elder for Cara, demonstrating the value of living authentically.

Lissette is a caseworker of Dominican descent tasked with guiding Cara through the Senior Workforce Program. Rather than strictly enforcing standard interview protocols, she patiently listens to Cara's sprawling narratives. Her willingness to let Cara vent transforms their vocational meetings into vital therapy sessions.

Ricardo is Cara's ex-husband and Fernando's father. Though initially kind, he becomes cold and violently abusive after Cara suffers multiple miscarriages. His escalating violence ultimately forces Cara to deliver her son alone and later flee to the United States for safety.

Hernán is Ángela's husband and the head cook at a hospital cafeteria. He applies Cara's frugal cooking lessons to create nourishing meals on a tight budget. He serves as a stabilizing, supportive presence for his wife and extends that support to his sister-in-law during times of tension.

Alexis is Fernando's roommate and companion. When Cara causes a scene at their door looking for her son, Alexis diffuses the situation by inviting her inside for coffee. He strikes a bargain with Cara, promising to alert her if Fernando is ever in trouble in exchange for her giving Fernando space.

Rafa is Cara and Ángela's brother. After his wife leaves him due to his drinking and abusive behavior, he moves in with Cara. He struggles with diabetes and relies heavily on his sister's care and keen sense of smell to monitor his deteriorating health.

Adonis is Lulú's son, who initially achieved traditional markers of success by securing a finance job and a house. When the housing market collapses, he loses everything and secretly incurs debt before moving his family into his mother's small apartment, a failure that deeply humiliates Lulú.

Patricia is Adonis's wife. Forced to move her family into her mother-in-law's cramped apartment, she attempts to maintain control by enforcing strict, modern rules for her children. Her child-rearing demands create significant friction with Lulú and Cara, who struggle to follow her instructions.

Alicia the Psychic is an online spiritualist who sends regular emails promising wealth, happiness, and cosmic alignment for a fee. Although Cara never sends her any money, she relies heavily on Alicia's predictions to maintain hope and find meaning during periods of intense economic uncertainty.

Tita is a long-standing neighbor in Cara's building who falls victim to the new management's aggressive gentrification tactics. Forced into a smaller, more expensive apartment over a minor lease violation, she works night shifts as a caregiver to make ends meet while raising her adult daughter.

Cecelia is Tita's adult daughter who has a developmental disability. Her condition requires constant supervision, prompting the building's community of older women to coordinate a schedule to watch over her while her mother works night shifts.

Julio is Ángela and Hernán's five-year-old son. His high energy and rowdy behavior frequently overwhelm Cara. When he misbehaves by dumping food, Cara's harsh disciplinary reaction triggers a major family conflict regarding parenting methods.

Yadiresela is Ángela and Hernán's daughter. She becomes the focus of Cara's intense protective instincts when a strange man asks for a photograph of her, prompting Cara to secretly tail the girl home to ensure her safety.

Sabrina is a teenage girl living in Cara's apartment building. Cara catches her in the stairwell sharing marijuana and kissing a girlfriend. Seeing the stark terror in Sabrina's eyes reminds Cara of her own son, prompting her to keep the girl's secret safe from strict parents.
