You will be given a definition of a task first, then some input of the task.
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: Ted took his wife for a romantic horse ride on the beach. 
 Initial Context: The two walked their horses for a while and then stopped to talk. 
 Original Ending: They set their horses up to a tree and sat down. As soon as they walked away, the horses got away and ran far. Ted looked at their restraints and saw that they were loose. 
 Counterfactual Context: The two walked their horses all the way to their beach house.
Output:
They tied their horses up to a tree and sat down. As soon as they walked away, the horses got away and ran far. Ted looked at their restraints and saw that they were loose.
