I notice much of his work is in how people look. It always balloons from there with our assumptions about them. Here he is a bureacrat in a suit but also mildly drunk the whole time, more of an anti-yuppie. She a stripper with a heart of gold.
I believe his character is meant to display a casual and banal cruelty. The son of privilege and means, but is a generational black hole.
It flips the expectation. Throughout it we think he is damaged beyond repair rather than the self-indulgent narcissist that he is. We also underestimate her real pain, thinking she is there to fix him.
Much of it only sets in after, it is like it was being constructed for our memories. Overall, Somai's final film has a quiet majesty to it.
