Given the task definition and input, reply with output. 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: Kay had a horrible migraine headache. 
 Initial Context: Since it was Sunday she decided to lay around until she felt better. 
 Original Ending: Every time light hit her eyes the pain increased. She found out her sleep mask on and lay down. Kay ended up laying down 8 hours before the headache ended. 
 Counterfactual Context: Kay laid around and the pain finally subsided.

Every time light hit her eyes the pain increased though when it came back. She found out her sleep mask on and lay down. Kay ended up laying down 8 hours before the headache ended.
