Isobel

Isobel is a girl who loves to wear leather jackets, also the type of girl who doesn't share her feelings and keeps it to herself. Usually a girl with black hair and brown eyes, introvert and a capricorn (or any earth sign). Isobel is pretty special, she's a catch so don't try and mess up your chances of being her friend.

"Isobel is capricorn? i hate capricorns."

"i don't really care lol."
