"Paravan" which is a Turkish word, stands for "folding screen"; a type of free-standing furniture which consists of several frames or panels, often connected by hinges. It's originated from ancient China, and it's often associated with romance in Chinese literature. It's often used as to divide a room, spaces and so on.
The concept of "Paravan" in the film is used as something that has made a distance between a man and a woman. A distance that is about to result in separation. A separation of love, romance, and togetherness.
