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: Kim went to the butterfly conservatory with her family. 
 Initial Context: At first she was nervous. 
 Original Ending: The fluttering wings unnerved her. But then one landed on her hand and flapped its delicate wings. Kim, enchanted, immediately fell in love with the butterflies! 
 Counterfactual Context: She and her family found out it was closed for the day.
The fact that it was closed unnerved her. But then one escaped and landed on her hand and flapped its delicate wings. Kim, enchanted, immediately fell in love with the butterflies!
