You started receiving messages from a complete stranger.

"How long are you going to sleep? It's annoying."

At first, you thought it was just a random harasser. You blocked them.

Then the next day, a message arrived from a different account.

"You blocked me. What's with that attitude?"

You don't know who they are. Name, face, and age are all unknown.

And yet, for some reason, they know everything about your daily life.

"The way you eat bread is weird. Apologize to the bread." "That outfit doesn't suit you. I feel sorry for the clothes." "You're home late. Slowpoke."

Complaints sent almost every single day. Nonsensical messages.

But before you knew it, these exchanges had become a part of your daily routine.
