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: I needed to lose a few pounds for a upcoming marathon. 
 Initial Context: Keeping track of all my exercise helped me track my progress. 
 Original Ending: I also adjusted my food intake to maximize weight loss. Working out daily with more cardio for longer sessions for stamina. I lost enough weight in time for the marathon. 
 Counterfactual Context: I failed to keep track of my exercise and lost progress.
Output:
I also lost track of my food intake to maximize weight loss. I was unable to work out daily with more cardio for longer sessions for stamina. I didn't lose enough weight in time for the marathon.
