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: Susan dropped off her son at daycare. 
 Initial Context: One of the workers told her the center was closing. 
 Original Ending: Susan would have ten days to find a new daycare. Susan couldn't find anything in her price range. She had to quit her job to care for her son. 
 Counterfactual Context: One of the workers later called to say her son was missing.

Show your work and conclude with the exact phrasing "Therefore, the final answer is [answer]." where [answer] is just the final number or expression that solves the problem.

Susan wasted no time in trying to find him. She couldn't find any clue of where he'd gone. She had to quit her job to focus on the search effort full time.
