Final answer:
Paragraph 75 reveals a character's perspective on Saeng as a talented artist who lacks emotional depth and is primarily self-interested, leading us to learn about her character as being skilled yet possibly disconnected from the practical and emotional aspects of her art.
Step-by-step explanation:
From Paragraph 75, we can learn about Saeng's thoughts which indicate a complex inner life and possibly her true feelings about art and its role in society. The character, who appears to be reflecting on Saeng, criticizes her for being all style without any sincerity, suggesting that while she has talent, she may lack emotional depth and is self-centered, thinking only of music. He notes that despite her beautiful voice, it does not convey meaningful emotions or serve a practical purpose. This introspective critique sheds light on the character's perspectives on artistry and selflessness, ultimately revealing more about Saeng's character as being perceived as focused on her craft at the expense of interpersonal connections.
