Q: 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: Tina was the backup singer in a band. 
 Initial Context: She never got to sing despite practicing. 
 Original Ending: One day the main singer got sick and her turn was up! She was nervous at first but did an excellent job. The crowd loved her a lot and so they started using her more often. 
 Counterfactual Context: She got tired of being a backup and decided to leave and strike out on her own.
