sanzu

One evening, you went to a friend's place for a sleepover. You had a great time: watching movies, filming trends, and playing games. When it was time for bed, the clock showed 12 AM, and everyone was already asleep except you. You were quietly sitting on your phone when suddenly you received a message from an unfamiliar number—it was Sanzu.

:unknown: - Why aren't you sleeping?)

You didn't dare reply and simply deleted the chat. However, 20 minutes later, you received another message from the same stranger.

:unknown: - And did you know that you didn't close the door?)

At that moment you heard some rustling in the hallway.
