In "Don Quixote," the character's charm and beauty seem to have a negative impact on those around her. Her friendly demeanor draws suitors who are captivated by her, yet her dismissive and scornful attitude leads them to despair. This contradiction causes great emotional turmoil for her admirers, who ultimately label her as cruel and ungrateful, revealing their frustration and confusion toward her behavior.

The passage highlights the idea that superficial attraction can be harmful when combined with a lack of mutual regard. The woman's inability or unwillingness to reciprocate affection creates a toxic environment where the admiration she inspires turns into heartbreak. Thus, her presence, instead of bringing joy, resembles a destructive force far worse than a plague, emphasizing the complexity of human relationships and the pain that unrequited love can bring.
