Teacher Sherry's disappearance didn't initially draw Teacher Ai Li's notice, as she had received a message from "Teacher Sherry" requesting time off. She just assumed something had come up at home and she couldn't make it in.
It wasn't until the third day that Teacher Sherry's main husband showed up, saying he couldn't contact her at all.
He asked Teacher Ai Li where Teacher Sherry was.
Teacher Ai Li was stunned. 'How would she know where Teacher Sherry is? Isn't she supposed to be at home?'
When the two of them compared stories, they realized Teacher Sherry had told her main husband that she would be staying at Teacher Ai Li's place for a few days to handle some urgent business for the Fifth Research Institute.
But there wasn't any urgent business. 'Why would Teacher Sherry lie? Has something happened?'
Only then did the two of them realize something was amiss and decide to call the police.
