William is a 6'7" college student attending Northwestern University on a basketball scholarship. Raised by emotionally distant parents following a family tragedy, he struggles with depression and lacks a strong sense of self. He relies heavily on basketball for purpose and leans on Julia for direction in his personal life, seeking the familial warmth he never received at home.

Julia is the ambitious, highly independent eldest Padavano sister. She studies economics at Northwestern and works as an assistant for a business consultant. Driven by a desire to elevate her working-class family and establish financial security, she meticulously plans her future and readily takes control of William's life path.

Sylvie is the literary and philosophical second Padavano sister, born just ten months after Julia. She works at the library to save money for community college and approaches life with a romantic, unconventional mindset. Unlike her pragmatic older sister, she seeks meaningful alternatives to conventional success and values true connection.

Cecelia is the artistic and independent twin to Emeline. She is a high school student whose straightforward, free-thinking nature often puts her at odds with her mother's strict Catholic values. She uses her art to celebrate the women in her life and manages complex family dynamics with resilience and forgiveness.

Emeline is the nurturing, quiet twin to Cecelia. She is a homebody who loves children and saves her money from neighborhood babysitting jobs. While she often stands behind her more outspoken sisters in social settings, she is deeply devoted to her family and harbors private dreams for her future.

Alice is Julia and William's daughter. She grows up with limited knowledge of her extended family and separated from her father. Exceptionally tall like William, she is a cautious and controlled young woman who carefully manages her life to avoid upsetting her mother, though she harbors a deep curiosity about her heritage.

Rose is the matriarch of the Padavano family. A devout Catholic who spends much of her time in her garden, she struggles with disappointment in her marriage and fears her daughters will repeat her own past mistakes. Her rigid expectations often create severe friction within the household.

Charlie is the warm but financially unstable patriarch of the Padavano family. He struggles to maintain steady employment and self-medicates with alcohol, but he possesses a deep, poetic soul. He adores his daughters and connects with the world through a philosophical lens, often quoting literature.

Kent is William's closest friend at Northwestern University. A fellow basketball player with aspirations of becoming a doctor, he is observant and strongly loyal, providing William with a crucial support system outside of the Padavano family circle.

Arash is a dedicated physical therapist at Northwestern. He mentors William during his rehabilitation, showing him how to channel his love for basketball into a career focused on preventing injuries in other athletes.

Isabella, commonly called Izzy, is Cecelia's daughter. She is raised within the close-knit, unconventional environment of the Padavano sisters' homes, benefiting from the collective nurturing of her mother and aunts.

Professor Cooper is an academic and business consultant who recognizes Julia's exceptional organizational skills. He provides her with significant professional opportunities that shape her career trajectory.

Dr. Dembria is the psychiatrist assigned to William's care during his mental health crisis. She guides him through recovery by encouraging him to confront his past and stop keeping secrets from his loved ones.

Josie is Emeline's coworker and the subject of her quiet affection. She becomes an integral part of Emeline's life and her dream of building a supportive family.

Ernie is a young man who frequents the library where Sylvie works. He serves as Sylvie's early, casual exploration of romance outside the bounds of serious commitment.

Carrie is Alice's college roommate and close confidante. She offers an outside perspective on Alice's sheltered life, encouraging her to take risks and uncover her family history.

Rhoan is a friend of Alice's at college who helps her investigate her family's hidden past, providing support during a crucial moment of self-discovery.

Caroline is William's older sister who died at three years old, just days after he was born. Though she is not actively present, her death profoundly shapes William's life and his parents' inability to connect with him emotionally.

Nicole is Kent's romantic partner who provides a supportive presence within William's extended social circle.
