Time Out says
This first feature by the director of March Comes in Like a Lion was a seminal film for Japan's emerging independent cinema in the early 1980s. A young woman falls insanely in love with her flatmate. Unable to voice her feelings, she tries to disrupt the other woman's existing love life by seducing her boyfriend - only to find herself pregnant by him. Filmed (almost entirely in long-shots) with remarkable delicacy and restraint, it gets inside the mind of a manic obsessive with near-hallucinatory intensity.
