Teacher:Given a premise, an initial context, an original ending, and a new ending, the task is to generate the counterfactual context that is aligned with the new ending. 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. The original ending is the last three sentences of the story. Also, you are given a new ending that can provide the new story with the same premise. You should write a counterfactual context to explain the small differences between the original and new endings. More specifically, a story context contains the general plot of the story. And a counterfactual context is a slight modification to the initial context. To sum up, you should write the second sentence of a story based on the premise(first sentence) and the new ending(last three sentences) of the story.
Teacher: Now, understand the problem? Solve this instance: Premise: When gay people tried to get the right to marry I supported them. 
 Initial Context: But they said that their marriages wouldn't lead to polyamorous ones. 
 Original Ending: I feel like they are just as bigoted as those who hate gay marriage. I don't know if I'll ever marry my boyfriend. But not having the option and being seen as lesser does hurt. 
 New ending: I feel like they are just as bigoted as those who hate gay marriage. I don't know if I'll ever marry my boyfriend. But not having the option and being seen as lesser does hurt.
