[image deleted] So now you can still know what I mean "for awile" without having watched. The romantic comedy's second ending veils and tragic actual ending. Substitute your favorite action, horror or drama that titillating viewers with a hope of a happy ending them dashes those hopes with a tragic ending. I mean substitute in reverse. Thelma and Luise would be a classic example. TGOT has us invested in the tragedy so much we are entertained by the utter failure of the main character ending. But then are given an greater emotional boost by the real ending which is unbelievably happy nevertheless. Trying not to spoiler.
