Definition: 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.
Input: Premise: Blake took out his revolver and cocked it. 
 Initial Context: He aimed at the target slowly but steadily. 
 Original Ending: He fired the revolver and a deafening roar howled through the canyon. When he looked at the target, no bullet holes were there. However, his trusted donkey, Fred, was dead. 
 Counterfactual Context: He aimed at the target but dropped it on accident.
Output:
The revolver went off when it hit the ground and made a deafening roar howled through the canyon. When he looked at the target, no bullet holes were there. However, his trusted donkey, Fred, was dead.
