404 is right.

There really is a serial killer.

I stared at the prank eyeball on the table.

What does the serial killer mean by placing dumplings at my door?

Is this a murder warning?

Does it indicate that I am the next target?

If it wasn't the work of the killer, then who did it? What are they trying to remind me of?

Looking at the photo again, I suddenly felt a chill down my spine.

I suddenly remembered.

There are no surveillance cameras in 501's house at all!

Not just 501, but the corridors, hallways, stairwells, and even the entire building have no surveillance cameras.

Because we often lose shoes and umbrellas, the group has repeatedly raised this issue, but it has never been resolved.

But the photo in my hand is clearly a screenshot from a surveillance video!
