The film presents a captivating psychological examination of therapeutic relationships and recollections, employing striking visuals, realistic conversations, and surprising developments to craft an absorbing narrative centered on Ruining and Xiao Yan’s connected psyches. Recognized for its exceptional sound design and writing, the movie skillfully obscures the line between what is genuine and what exists within the subconscious, prompting audiences to doubt the veracity of events. While it comes remarkably close to perfection, a small problem with casting in one essential flashback momentarily diminishes the sense of authenticity.
