Given the task definition, example input & output, solve the new input case.
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.
Example: Premise: Susie was sitting on her barstool. 
 Initial Context: She kept kicking the counter with her feet. 
 Original Ending: Suddenly, her kick sent her falling backwards. The chair hit the ground with a thud and broke. Susie hurt her head and was really scared. 
 Counterfactual Context: She kept herself steady with her feet.
Output: Suddenly, an earthquake sent her falling backwards. The chair hit the ground with a thud and broke. Susie hurt her head and was really scared.
The generated new ending is perfect. It considers the counterfactual context and changes required parts in original ending.

New input case for you: Premise: Bart challenged Nellie to go a week without her phone. 
 Initial Context: Nelli accepted the challenge. 
 Original Ending: Bart checked in on her every day. She always reported success and was totally silent on social media. She actually cheated the challenge each day with phone web browsing. 
 Counterfactual Context: Nelli said "no way!".
Output:
Bart did the challenge anyway and Nelli checked in on him every day. Bart always reported success and was totally silent on social media. He actually cheated the challenge each day with phone web browsing.
