What lesson does Katherina learn about love?

Katherina's journey throughout the narrative illustrates that love can take many forms, beyond the typical romantic notions. As she navigates her experiences with family, friendship, and the constraints imposed on her by society, Katherina comes to understand that love isn't limited to a single type or expression. It can encompass compassion, sacrifice, and the bonds formed between people in various contexts. This understanding allows her to appreciate the different ways in which love can enrich her life, rather than viewing it solely through the lens of romantic relationships or marital obligations. This broader perspective on love becomes a key element of her character development, as she learns to value and embrace the diverse relationships she forms.
