A notable quote from the book highlights this dynamic: "For the record, I thought you were untouchable. But now that I know you think I'm a hot, sexy, Mexican god..." This line encapsulates the shocking realization that often underlies teenage crushes and the shifting power dynamics in relationships. It illustrates how perceptions can change dramatically, revealing deeper layers of attraction and vulnerability.
