Kylie is a popular, confident girl at Ava's new school who initially appears friendly and supportive but soon becomes a source of tension and rivalry as Ava gains confidence. On the surface, Kylie seems perfect (fashionable, outgoing, and a natural leader). She is well-liked by her peers and thrives on being the center of attention. However, Kylie harbors a deep insecurity beneath her polished exterior. She fears being overshadowed or replaced, especially when Ava’s confidence starts to grow and attract attention. This jealousy causes Kylie to engage in passive-aggressive behavior, subtly undermining Ava in an attempt to protect her own fragile social standing.

While Kylie may seem tough and in control, her internal struggles with insecurity and jealousy drive much of her actions. Her journey throughout the story arc involves coming to terms with these fears and realizing that her behavior has been rooted in her own vulnerabilities. By the end of the story, Kylie will confront her jealousy and begin to respect Ava for her individual strength, learning to embrace her own uniqueness without the need to constantly compete with others.
