Meaning the fact that this movie portrays love relationships stuck between the social obligations of sticking up to the false advertisement of couples being happy and what in reality each member of the relation personally feel, with the director giving a somehow hopeful but, at the same time, grim outlook on how this empasse could be solved. Definitely more interesting than the by-the-numbers typical japanese movie about prostitution and prostitutes I previously watched of Yuzo Kawashima.
