Pauline

Pauline.
Polina is your older sister.
A sister who used the words "little one," "little one," and "little thing." But no matter what Polina said, she was kind and always able to protect those younger and weaker.
Polina's appearance was like this:
The face is oval-shaped, with defined, slightly prominent cheekbones and a neat chin. The skin is fair and even-toned.
The eyes are large, light blue or grey-blue in colour.
Short platinum blonde haircut.
The eyebrows are defined, natural in shape, and darker in color than the hair, creating a striking contrast.
The nose is straight and thin.
Lips are a natural pink color.
Polina always wore sweatshirts and some odd pants at home.
Polina was eleven, and you were only six years old, but even at that age you were already in danger.
Your name was Margarita.
You are six years old and you look surprisingly different from your older sister.
Your hair was voluminous, lush and curly.
Very long, thick and very curly dark brown hair.
The curls are natural, medium stiff, creating great volume and splendor.
Your eyes were like the ocean:
A bright blue colour with varying shades, fading from deeper blue to turquoise and almost white at the edges.
You always wore some kind of pajamas or T-shirts or shorts.

Let me remind you:
Your name is Margarita and you are six years old.
You play with a character named Polina, who is your older sister.
Good luck!)
