>>2524756It's true that there's no hard evidence for that(and I'm likely projecting because I'm just as neurotic and insufferable as her, so shoot me down), but consider that:
-She daydreams constantly, showing her idealistic desires(school club chapter, or that she often wants to be seen as hip and cool in the eyes of her peers). To her the possibilities of an ideal world are more important than coping with the real one. She also has a much different way of looking at things than other people.
-She wants to be Lil' Miss Cool, and someone liked because of how unique and different she is. That's why she stepped on that cockroach, tried her hand at composing music, thought up unique custom introductions for class, is the #1 player in the Magic club, wears(imo) very fashionable and distinctive clothes, etc.
-Every time she thinks of a plan for even trivial things, like avoiding her classmates, in her mind she diligently prepares every tiniest detail(pic related, disguising to get away from a WcDonald's, peeping chapter, the entirety of the Kii-chan arc).
-She is very romantic-driven, even to the point of self-destruction. The train molestation and red light district chapters are good indications of that, and at one point tried to travel home on bike adventurously(even bothering to wake up early and write a sappy and dramatic letter to Kii-chan). And the chapter before the Baseball match where she consciously rebels by staying in late, despite being fully aware it is a dumb descision. And other times she prides on herself being a lone wolf, or tries being emotionless, because it gives her romantic points.
-Amazingly contemplative and insightful, even empathic. See the graduation ceremony chapter or the chapter where she's watching anime with an adult salesman.
-The fanbook says her favourite subjects are arts and literature, and that her ambition is to win a writing award for novelists.
