Given a premise, an initial context, an original ending, and a counterfactual context, the task is to generate a new story ending aligned with the counterfactual context and as close to the original ending as possible. Each instance consists of a five-sentence story. The premise is the first sentence of a story, and the second sentence, which is the initial context, provides more information about the story's context and the story's general plot. The original ending is the last three sentences of the story. Also, a counterfactual context is a slight modification to the initial context. You should write a new story ending that edits the original story ending as little as possible to regain coherence with the counterfactual context. To sum up, you should write the last three sentences of a story based on the premise(first sentence) and the counterfactual context(second sentence) of the story.

Premise: Brady buried a piece of coal in hopes it would become a diamond. 
 Initial Context: Brady often thought of that piece of coal. 
 Original Ending: As he got older, the piece of coal was forgotten. Brady was grown up and remembered the coal buried. He never dug the piece of coal up. 
 Counterfactual Context: Brady dug up that piece of coal.
As he got older, the piece of coal never became a diamond. Brady was grown up and remembered the coal. He was sad he dug the piece of coal up too early.
