What does Ocean express envy over concerning Constance?

Ocean expresses envy over Constance's care-free attitude. This choice highlights the essence of Constance's character, which represents a sense of freedom and lack of burdens that Ocean feels she lacks. Throughout the narrative, Constance embodies a lightheartedness and an unencumbered approach to life that stands in stark contrast to Ocean's experiences and feelings. This carefree nature allows Constance to navigate challenges with an ease that Ocean admires but struggles to achieve herself.

The other options, while potentially significant in their own right, do not capture the core of Ocean’s emotional response toward Constance. The social life or academic achievements do not evoke the same level of personal longing and desire for the kind of relaxed existence Constance enjoys. Similarly, family connections might bear importance in the story, but they do not fully reflect the specific admiration that Ocean has for the way Constance approaches her life without the weight of concern or responsibility.
