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: Last summer Adrian's house caught fire. 
 Initial Context: It burned to the ground before the firemen could arrive. 
 Original Ending: He lost everything he owned. He knew it was going to take a long time to get it all back. But his family made it out alive, so he knew he'd be alright. 
 Counterfactual Context: The firemen arrived and there was very little damage done.
Output:
He was happy he didn't lose everything he owned. He knew it would have taken a long time to get it all back. He was lucky his family made it out alive.
