Both of them looked at the back door as if by an unspoken agreement.
Zhu Qingyue seemed startled, standing still in place; whereas Xu Xiangyang was holding his breath, subconsciously raising his leg, ready to grab someone and run away.
...But there was no one in that direction.
Not a single shadow to be seen, just a gust of night wind that blew into the classroom, causing the door to sway slightly.
"Is someone really playing a prank?"
Zhu Qingyue murmured, her voice inevitably trembling a bit.
"You wait here, I'll go outside to check the situation."
Xu Xiangyang didn't wait for her to express her opinion, and headed straight to the door.
The classroom door was already ajar, and he stood by the doorframe looking left and right; the staircase bathed in dim yellow light, the corridors submerged in darkness, all empty.
Xu Xiangyang took a deep breath and closed his eyes.
