After the girls walked out, they went straight to the infirmary.
The door of the infirmary was closed, and it was already dark outside. The lights in the infirmary were on, and the few girls approached; they giggled among themselves, none of them daring to be the first to knock and enter.
"Aiya, you go first."
"No, no way!"
"You go. Just say that you're sick and want Dr. Gu to take a look."
"Well, why don't you go?!"
"Shh! Did you hear something?"
"Huh? Hear what?"
The few of them quietened down and listened carefully.
There really seemed to be noise.
It came from the infirmary.
Intermittently.
"Hold it!"
The few of them were stunned, and did not dare to move.
When they regained their senses, they could not help but take two steps towards the infirmary door. The voices inside became clearer.
"Don't move!"
They looked at each other.
"Where do you think you're running?!"
