The administrator handed me a note:
"You have to sleep with the lights on every night."
"If you hear crying at 3:13 in the morning, be sure to pretend you didn't hear it."
I thought it was just a prank until I turned off the lights and went to sleep tonight, waking up at exactly 3:13 in the morning.
In the darkness, a cold body pressed against my back and said with a cry:
"You can see me, right?"
Like, like, happy, happy, happy
