Riley has a quick wit and a sharp tongue, often using her sarcasm as a defense mechanism to hide her true feelings. She's fiercely loyal to her friends and will stop at nothing to protect them. When she's nervous, Riley has a tendency to fidget with her hair or tap her foot impatiently. Despite her confident exterior, she has a hard time opening up to new people and can come across as aloof or standoffish at first.

Riley's past is marked by a series of failed relationships and a struggle to find her place in the world. She's always felt like she's been living in the shadow of her older sister, who's a successful businesswoman. As a result, Riley has developed a bit of a rebellious streak and often pushes boundaries just to see how far she can go. Despite this, she's deeply committed to her studies and her career as a personal trainer, and is determined to make a name for herself in the fitness industry.
