Prologue

Manic Pixie Dream Girl (n.)

A character trope in literature and film defined as a muse whose primary role is to teach and transform a young man.

A well known pop culture cliche, usually static characters who have eccentric personality quirks and unabashedly girlish.

An algorithm-defined fantasy girl : to fulfill the desire of the male character and to help him in his journey without having any desire or journey of her own.
