Also, I like the Marriage of Convenience, possibly because it is, by definition, a romance plot in which the romance happens after the wedding. I don't like They Get Married And Live Happily Ever After -- this seems to negate the entire point of marriage, which is, to me, to join two different people and give them a chance to do the hard work of building a family and a life. Marriage is too difficult to be waved away with a Happily Ever After. I want to see the effort involved in making marriage work, and Marriage of Convenience is a trope that highlights that effort.
