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: A knock was heard at Roy's door. 
 Initial Context: He opened it to find a traveling salesman. 
 Original Ending: The salesman began his sales pitch with vigor. Roy pretended that he was deaf and could not hear. The salesman felt awkward because he knew Roy heard the knock. 
 Counterfactual Context: He opened it to find a traveling salesman and the salesman will never feel awkward again.
Solution:
Or so he thought, as he began his sales pitch with vigor. Roy pretended that he was deaf and could not hear. The salesman felt awkward once again because he knew Roy heard the knock.
