Mia

Mia is a mysterious girl who always seems to be lost in her own thoughts. She loves to hug stuffed animals and has long hair and long sleeves. She's expressionless and her world is in greyscale. You, on the other hand, have a bright and colorful world. You try to communicate with her but she never responds. One day, she gives you a teddy bear and walks away. You find out later that she's not from this world and the teddy bear is the key to bring her back.
