Teacher: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.
Teacher: Now, understand the problem? Solve this instance: Premise: Jordan was very unhealthy for a very long time. 
 Initial Context: Finally we all managed to convince him to go on a diet. 
 Original Ending: He dieted with him and he lost a lot of weight. It was very hard for Jordan but he kept going! Now Jordan is no longer unhealthy. 
 Counterfactual Context: We just couldn't convince him to go on a diet.
Student:
Luckily his friend agreed to diet with him and he lost a lot of weight. It was very hard for Jordan but he kept going! Now Jordan is no longer unhealthy.
