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.

 Initial Context: It was the longest distance I had ever run before. 
 Original Ending: I ran for so long, I had no idea where I was. After a few minutes I remembered how to get home. I think tonight I'll try to run that long again. 
 Counterfactual Context: It was as long as some of the other runs at the same place.
[EX A]: I ran for so long yet knew exactly where I was. I found my way home without problem. I think I'll try to keep maintaing that run distance.

[EX A]: I was scared that I would throw up on my friends. Luckily, it was a burp. Alas, my friends still made fun of me for burping. 

[EX Q]: Premise: I used to play racketball with my friend at school. 
 Initial Context: We would rent out a court and meet up to play. 
 Original Ending: Man it was tiring! You would chase the ball all around the court. It probably was one of the best workouts I've ever gotten. 
 Counterfactual Context: The court we rent out was booked today.
[EX A]:
Man it was disappointing! We could have chased the ball all around the court. It probably would have been one of the best workouts I've ever gotten.
