The quote reflects on the nature of perception and the illusions people create in their relationships. The idea that someone's enchantment or "magic" can fade once they are free suggests that these are temporary illusions that often mask the reality of one's true self. This highlights the transient nature of attraction and the superficiality that may come with it.
In contrast, the speaker acknowledges that the mistakes and errors perceived by others can leave a lasting impression. It points to the deeper truths about identity and how individuals are often misunderstood or misrepresented. The statement "we are not always what we seem" emphasizes the complexity of human nature and the dissonance between appearance, reality, and aspirations.
