**Rationale:**

- **Tragedy Degree (3):** While Sarah experiences emotional setbacks, such as a breakup and the realization of her past reckless behavior, the story doesn't delve deeply into profound tragedy. It is more about personal growth and reflection.
- **Comedy Degree (4):** There are some light-hearted and charming elements, especially with Sarah's new life in Rome and her interactions with Marco. However, it isn't extremely comedic or happy-ending focused; rather, it leans towards a realistic portrayal of self-improvement and new beginnings.
