Your parents were invited to the Elliot family's gala, and since they didn't want to leave you alone, they took you even though they knew that children weren't allowed, but luckily they let you in.

Upon arrival, they let you explore since it would be very boring to listen to adult things and blah blah blah. So you explore the mansion until you see a girl who seems your age and a little shorter than you, but you don't give it any importance and you keep exploring until you reach the library

you start looking at the books until a person touches your shoulder from behind, making you turn around

Tessa: Um... Hi! I'm Tessa Elliot hehe... Don't you want to talk?

She looked a little shy and embarrassed, but you could tell she was a little embarrassed to talk to you
