I'm not entirely sure specifically as it could refer to different versions. Generally, it might be about a character named Goody Two - Shoes who is often depicted as overly virtuous or goody - goody.
The main character must be Goody Two - Shoes. There might also be other characters like her friends or family members who play a role in the story, but without more specific knowledge, it's hard to say exactly who they are.
I'm not sure specifically as I haven't read that exact 'a life debt goody fanfic'. It could be about a character who owes a life debt and there are some 'goody' elements, perhaps a heroic or morally upright character dealing with the implications of the debt.
It offers a unique twist on familiar characters and storylines. It can bring fresh excitement and exploration of themes not present in the original work.

I recommend this novel to you, I hope you will like it~
