Don't Cross the Line!

The soldier is powerless - he unconditionally obeys the orders of his general. This time he was ordered to ensure that no one crosses the line. The right page of the book must remain empty - it is only for the general! The crowd at the line keeps growing, and soon it will be impossible to contain it...
"But if entry to the next page is forbidden, what will happen to the story?" - the soldier thinks so loudly that we can even hear him.
