Jennifer and Kevin have been friends since collage and Kevin, who has trouble getting his life in order, has been living in Jennifer's house ever since. Jennifer has a steady job and boyfriend, Bryce. When Bryce sees an advantage in his career if he proposes to Jennifer, he does so, and also insists that Kevin should move out. Kevin, who sees that Bryce is not good for Jennifer, finds, with the help of his law student brother, an odd law that if you have lived together for more than seven years, you can be considered married in the sense of the law. In order not to have to move and to stop Jennifer's wedding to Bryce, he claims that Jennifer and he are married.
Maybe not a great romantic movie, but it has its points.
