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: Eva needed to lose a few pounds over the summer. 
 Initial Context: But it was so hot and she just couldn't refuse ice cream Popsicles! 
 Original Ending: Then a friend told her to freeze fruits and yogurt to snack on. The treats were still cold and sweet, but much healthier. By the end of summer, Eva had lost eleven pounds! 
 Counterfactual Context: She drank lots of water and it kept her hydrated and full so she wasn't always wanting to eat snacks.
Output:
Then a friend told her to freeze fruits and yogurt to snack on. The treats were cold and sweet, and healthy so she wouldn't feel guilty eating them. By the end of summer, Eva had lost eleven pounds!
