A. FULL. YEAR. OF. TROPES!
Some Thursdays will have 2 tropes, some will have 3, but I think the majority will have 1 that's really popular.
Descriptions will be pulled from TV Tropes and a link provided if you want more information.
The rules? They're simple. Write at least 250 words or create 2 icons/1 banner. Anything from suggestive to outright porn is allowed.
This week there's 1 trope, but I think it's pretty popular!
Marriage of Convenience: "Many people marry for the wrong reasons, among them: 1 - to overcome loneliness; 2 - to escape an unhappy parental home; 3 - because they think that everyone is expected to marry; 4 - because only 'losers' who can't find someone to marry stay single; 5 - out of a need to parent, or be parented by, another person; 6 - because they got pregnant; 7 - because 'we fell in love', ... and on goes the list."
— Bruce Fisher and Robert Alberti
In Real Life, Western citizens of the twenty-first century predominantly Marry for Love. In fiction, that normally-tiny proportion of other marriages is inflated because of the intense comedic, dramatic and tragic potential.
That is, of course, in Western nations: Arranged Marriage is still not unusual in many other countries; it can still be a form of marrying for convenience, though, typically when a person agrees to an arranged marriage in order to get the arrangers to stop pestering them once they've resigned themselves. In other cases, like in media where the featured arranged marriage is not opposed to, it is simply fulfilling a convention of that media and/or its country, and so will probably not be a Marriage Of Convenience.
Often, a marriage of convenience is a mutually beneficial agreement, with both parties profiting from the binding - it may even involve a contract - but not always. Sometimes, only one of the partners may be in it for something other than love.
An expectation is that one or both of the people will fall in love with the other. It is also often a convention used to get two friends who are in love with each other to realize it. Then it may become a Perfectly Arranged Marriage.
I definitely recommend reading up on this one for more examples to help you if you want to write this one.
