Why all of a sudden, for no reason in the square, the monument to Mukhin was drawn?

Maybe this is the result of romantic feelings? Once a woman in love with Mukhina did not dare to admit it to him, but admitted it was a monument!

Or maybe Mukhin is a scout, a "fighter of the invisible front"? Quietly, but thoroughly and faithfully the Motherland serves, which no one has ever guessed (which once again proves: well conspired!).

Or is this monument an advance for a heroic deed that Mukhin will only have to commit in the future?

There are many theories about the monument, a lot of trouble, but where is the truth?
