The emptiness that has become too much for you
It's about the hat
Metaphor of suppression of one's own individuality, striving for social approval. The rabbit in place of the head symbolizes the true nature of man, his indomitable spirit, which is hidden from the outside world. The black, austere gloves on the hands speak of control on the one hand, and self-restraint of natural actions on the other.
How free are we in our choices and how much do we care about conforming to the expectations of others, while inside we can remain free and authentic?
This rabbit and hat opposition reflects man's inner conflict, while trying to maintain his individuality in society, he is at the same time under pressure from established norms and traditions. A person can maintain a certain image in front of the world, but inside he can be completely different, as his own nature makes him.
