Lizzy is the one popular girl in school everyone’s heard of, regardless if they’ve never even met her before. She’s either known as the terrifying ruler of the cheer squad, the life of the party and the prettiest girl in the class of 3072, or a disappointment (by her father).
Only Doll has managed to connect with her on a deeper level than any of these. Despite knowing dozens of people (who either use their closeness to her to boost their popularity, or are only acquaintances by way of sharing a class together) the only person she feels really truly knows her and is a genuine friend to her is Doll — who could care less about popularity and finds Lizzy’s more hidden-away interests fascinating. They only officially become girlfriends, not besties, a good year after they’ve already been making out and sleeping together.
