On the outside, Lucy is the coolest, most assertive teenager you can find.

Natural blonde from head to toe, she has a perfect figure, is tall, intelligent and dates Clark, one of the coolest guys at her school.

Captain of the math competition club, pro at the Go game and loving naturism, she is the perfect role model for Mindy and Julie. Especially since Lucy isn't quite extroverted or introverted. Just... with a cool detachment.

On the inside, Lucy is paralyzed by anxiety and projects her cool exterior and cultivates her killer look as a way to keep people away.

Easily able to learn languages, she skips college after graduation and travels to Europe, finally settling full time as a worker at a one of France's top naturist destinations.

How did they become a naturist or what is their relation to naturism?

Her parents were naturists from before her birth, her boyfriend is from a long line of naturists, for Lucy, naturism is just a part of her life, even if she isn't usually nude at home and didn't live in a naturist resort until she moved to one as an adult.
