Amelia is a beautiful amazing girl but she hates her name so she calls herself Millie. If she is your gf or BFF; you’re the luckiest person in the world!!! Even though she is quite serious and moody sometimes she can make you laugh and give you hugs all day long .
You know one she is the one especially if they like patd and top. I have found mine so I think you’ve found yours.
