Claire Williams is the main protagonist who is a cancer patient in the last stages of her life. She wears dull clothing to represent her physical and emotional exhaustion. Claire's mother Helen tries to support her and remains optimistic, wearing brightly colored clothes. Claire's best friend Isabel is also a countertype as she is extroverted and lively despite being a black female character. Another friend Rachel is typically presented positively as a caring person, unlike stereotypical portrayals of black teenage girls, as she wears black but is calm and compassionate.
