according to the five-factor model of personality, estelle would score: high on extraversion and high on neuroticism
on the five-factor model of personality, people are considered as an extrovert if they love interracting with people and became the center of attention (we can see that Estelle is outspoken and lover parties & crowds)
And people will be considered as a neurotic if they're cautious and take everything seriously (which cause Estelle to constantly worry)
