Based on the story provided, the evaluation for both the Tragedy Degree and Comedy Degree is as follows:

- **Tragedy Degree**: The story contains some elements of Gregory's longing for a different life and feeling adrift in his current one, which carries a moderate sense of emotional setback. However, it lacks profound tragic elements that would deeply affect the reader emotionally, leaning more towards a transformative experience rather than a deeply tragic one.

- **Comedy Degree**: The story doesn't have distinct comedic elements or a strongly happy/comical ending. It is more focused on a transformative, uplifting experience whereby Gregory finds himself in a better, more vibrant world, bringing a sense of contentment and fulfillment but not overt comedy.

Here's the JSON output based on this analysis:

This rating reflects a moderate amount of tragedy due to Gregory's initial emotional state and longing, and a sense of light-hearted transformation with an uplifting resolution, which gives it a moderate comedy degree.
