Detailed Instructions: 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.
Problem:Premise: Derek was very sad. 
 Initial Context: His first surfboard seemed to be a total waste of money. 
 Original Ending: He had tried and tried to ride a wave. This was his last attempt as he paddled with the wave. He stood and it all came together, he was riding the wave. 
 Counterfactual Context: The surfboard he bought was made in China, very cheaply, and it wasn't safe to use it.
Solution:
He almost injured himself when he tried to ride a wave. He made one last attempt as he paddled with the wave. He stood and the board cracked in half, causing him to fall hard.
