Sydney is a college student pursuing a degree in music, though she contemplates a shift to psychology. Her empathetic and reflective nature makes her attentive to the complicated dynamic she has entered with Ridge. She harbors guilt over previously kissing Ridge while he was with Maggie, motivating her to act with grace and establish a peaceful arrangement among their friend group.

Maggie is a 24-year-old woman living with cystic fibrosis and diabetes, conditions that force her to think constantly about her mortality. She recently ended a six-year relationship with Ridge but relies heavily on him as her primary caretaker and support system, as she lacks other family. She fluctuates between a desire to live boldly and a fear of getting close to others due to her medical reality.

Ridge is a deaf lyricist and musician in the band Sounds of Cedar. He is highly empathetic and protective, traits that often leave him feeling torn between his devotion to his new girlfriend and his deep sense of responsibility toward his ex-girlfriend. He relies on American Sign Language, text messaging, and songwriting to express his complicated emotions.

Jake is a cardiologist, a skydiving instructor, and a single father who shares joint custody of his teenage son. He maintains a healthy, amicable co-parenting routine with his ex-wife but seeks a more passionate, all-consuming romantic connection. He is drawn to Maggie's spontaneity and remains steady even when she exhibits inconsistent behavior.

Warren is Ridge's best friend and roommate, known for his blunt, unfiltered communication style. He previously dated Maggie and remains fiercely loyal to her, frequently stepping in to assist Ridge with her medical emergencies. His directness often serves as a catalyst for the friend group to confront uncomfortable interpersonal dynamics.

Bridgette lives with Warren and Ridge, bringing a volatile and unapologetic energy to the household. She possesses a brash exterior that often reads as hostility but stems from her intensely passionate nature. She fiercely guards her relationship with Warren and expresses strong opinions about the shifting social circles within their apartment.

Brennan is Ridge's brother and bandmate in the musical group Sounds of Cedar. He sings the lyrics that his deaf brother writes and regularly hangs out at the apartment, contributing to the communal atmosphere of the friend group.

Tori is Sydney's former best friend and roommate. Her past infidelity with Sydney's boyfriend shattered their friendship and continues to serve as a reference point for Sydney's own fears about loyalty and betrayal.

Hunter is Sydney's ex-boyfriend. His past affair with Tori deeply wounded Sydney and caused her to move out, inadvertently setting off the chain of events that brought Sydney and Ridge together.

Justice is Jake's teenage son, whom Jake shares with his ex-wife, Chrissy. He has an easy, open relationship with his father, often talking to him about life and relationships.

Chrissy is Jake's ex-wife and Justice's mother. She and Jake had Justice when they were teenagers and stayed together for twelve years out of mutual respect and responsibility before recently deciding to separate peacefully.

Cody is Justice's friend who occasionally spends time at Jake's house.
