In a closed, angular, square room.

At midnight, four people stand in the four corners, facing the wall.

Starting with player ①,

they move along the wall in a clockwise or counter-clockwise direction.

When player ① moves to the next person's position (player ② in the image),

they must tap player ② on the shoulder and stay in player ②'s position.

Player ②, after being tapped, then moves to player ③ in the same manner.

When someone moves to the next corner and there is no one else in that corner,

they must indicate "Nobody's here."

This is usually done by coughing loudly and then continuing to move.

Normally, in each loop, there will be a corner that is empty.

However, sometimes, after many loops, no one indicates "Nobody's here."

This indicates that there is no empty corner, and the continuous sound indicates that someone is always moving.

This behavioral pattern only continues when there are only 5 people.

So where does the extra "person" come from?

Uncanny Human: Four Corner tells the story of an uncle and three other kids playing a "four-corner game" in an abandoned house.

Unlike the original game, many anomalies occur during the loop: a suddenly appearing classroom, a hanging corpse, walls made of flesh and blood...

And... the fifth person mentioned in ghost stories...

Can you find me?
