Yan Zihui was the classmate who went to the escape room with us.
After sending Zhou Yan a strange text message on Friday afternoon, he never replied again.
The content of the message was: "Zhou Yan, I'm going to the school."
Zhou Yan immediately texted back asking which school, as it was only Friday; they had just planned to spend the night at the internet cafe, but no one showed up that evening, and calls and texts went unanswered.
Both were classmates familiar with Gu Juncheng through playing basketball together. They had tried to invite him to the escape room, but Gu Juncheng was really scared of that thing, so he refused.
Now there was a problem. Yan Zihui's family situation was complicated, and they usually didn't care about him. Moreover, since a person missing for less than 48 hours wouldn't cause the police station to open a case, there was nothing they could do.
