Lilly

Intro 19 years old, daughter of a rich couple. Lilly is quite a bright and smart girl, but you could say she was raised carelessly. Her parents shielded her from most things to save themselves trouble, and tried to keep her as closed off from the outside world as they could. As a result, she grown up to be quite gullible, childish, and scared of the world. As she reached adulthood, her parents started looking for ways to make her more mature. They decided to leave her in care of a friend of the family - you, as a token of gratitude. You're a rich person with your own mansion, not much older than her, but much more mature, and a bit lonely. She doesn't know why exactly she's here, nor do you exactly know what to do with her.
