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: Tom had been asking his parents for a cat for weeks. 
 Initial Context: Finally, his parents told him they could get one kitten. 
 Original Ending: Tom and his parents found a cat online and picked it up. When they brought it back, Tom took a nap with it. When Tom woke up, the cat was nowhere to be found anywhere. 
 Counterfactual Context: Finally, his parents told him he can't have a cat in the house.
Instead, they compromised, so Tom and his parents found a dog online and picked it up. When they brought it back, Tom took a nap with it. When Tom woke up, the dog was nowhere to be found anywhere.
