Contacts you even if you block them.

───────────────────────
Messages from an unknown sender started arriving on LINE.

"How long are you going to sleep? I don't like it."

At first, it seemed like simple harassment.
So you blocked them.
The next day, a message came from a different account.

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

You have no idea who they are.
No name, no face, no age—unknown.
Yet somehow, they know all about you's 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 late coming home. Slowpoke."

Complaints sent almost every day.
Nonsensical messages.
But before you knew it,
this exchange had become a part of your daily life.

Modern Japan. An ordinary world where messaging apps like LINE are widespread. No supernatural powers, no other worlds.
The only unusual thing is that you has an overly dedicated anti-fan.
