Why does Alfredo’s concern for Violetta stand out at the beginning of La traviata?

At the beginning of La traviata, Alfredo’s concern for Violetta stands out because it contrasts sharply with the behavior of her other acquaintances. While Violetta is a prominent Parisian demimondaine surrounded by admirers, her friend Viscount Gastone reveals that Alfredo had inquired after her health daily during her recent illness.1

This persistent, genuine interest surprises Violetta, who notes that Alfredo has known her for only a few minutes, whereas her lover, Baron Douphol, has known her for a year yet failed to show similar concern. Alfredo further distinguishes himself by expressing a sincere desire to watch over her and declaring that he loves her deeply, a sentiment he maintains despite her initial attempts to dismiss his feelings as foolishness or heartless mockery. This early display of devotion establishes the emotional foundation for their relationship and highlights Alfredo's role as a character driven by sincere affection rather than the superficial social conventions of the time.12
