i think Millie is just really cool. she does't have to try hard to seem interesting or likeable, she's just really effortlessly cool in a way i think a lot of people want to be. she's really emotionally mature and has a lot about her. i'm normally skeptical about girls who are pretty much only friends with boys, as they tend to be massive internalised misogynists and i also got cheated on with one of those girls lol. but Millie seems like she genuinely just gets on with everyone, she seems like a really lovely girl and deserves a lot of happiness.
