Because they knew about some things involving Xiao Yifei before, they left, but they didn't expect he went to rescue someone who was kidnapped. The most important thing is, now Xiao Yifei has disappeared, which is enough to make everyone worried. So, for a moment, everyone tried to figure out where Xiao Yifei went.
At this point, Liu Rui seemed a bit clueless because he guessed that maybe Xiao Yifei went to have a date with the girl he rescued, so he didn't return. But this idea was quickly denied by Hua Xiangrong because if that were the case, it wouldn't be possible for the phone not to get through.
This point was also confirmed by everyone: Xiao Yifei definitely did not intentionally not return. Knowing these things, everyone began to ponder why Xiao Yifei actually went missing. Since it wasn't that he didn't want to come back, someone must have restricted Xiao Yifei's movements.
