This painting is dealing with the complexity of romantic relationships.
The couple seems to be hugging tightly and forming one loving unit but is their love truly that strong? truly real?
The red figure seems to be more devoted to the other, it's clinging to the blue figure fully devoted while the blue figure is gazing aside...
Is the blue figure not devoted to relationship as the other? is it looking for something else? or maybe it's just being suffocated by this tight relationship and needs some space?
