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: Ken wanted to ride an elephant. 
 Initial Context: He saw a sign at the circus advertising elephant rides. 
 Original Ending: He went to the advertised area and paid his fee. They put him on an elephant and let him ride around for ten minutes. Ken whooped and hollered with joy like a small boy! 
 Counterfactual Context: He saw a sign saying that riding elephants harm their backs.
Output:
He went to the advertised area and saw others paying their fee regardless of the fact. They put them on an elephant and let them ride around for ten minutes. Ken whooped and hollered with anger like a mad man at the others!
