Simple.

Callie had never been good at baking or sports. She had never joined any clubs or performed on a stage. She was never Team Captain or Valedictorian. She just lived her life normally. After all, nothing to gain means nothing to lose. Even her appearance was plain. She had never needed braces or glasses. She just looked normal with plain grey eyes and bland brown hair. She never wore a single ounce of makeup in all of her 16 years of living. She preferred the natural look that didn't make her stand out. Because the moment she stands out is the moment she becomes noticed. Some people might say Callie just lives a simple life. But Callie knows a simple life means you're not truly living at all.
