I saw an asian film around 2010. It was about a shy girl who cooked food in her kitchen and went to work. One day she met a guy on her way to work and they started dating. They cooked food together and and at the table and weird things would happen like the table would be bumped and they would notice but not do anything about it or a vase would fall off a table again they would notice it but not do anything about it. Later in the movie you find out she was imagining the whole relationship and she had him tied up and he was the one knocking the stuff around trying to escape. The police break into her place and knock down a wall and see him tied up in a chair sitting at a table in this room that she imagined them eating at.

I cant remember the name of this movie but i would like to add it to my collection. Can someone please help.
