It would help if you would write your questions in actual English. When you don't we have to guess what you are trying to ask. I'm guessing that you were trying to ask, "What does the planned wedding between Paris and Juliet become?" "Plan wedding" doesn't mean anything unless it is a wedding between two blueprints.
