The part of the movie where the person that's in love finds out that the other person had a "past", despite the past not really being relevant to the love story.
Let me explain:
The movie I have seen last night had a struggling writer that fell in love with his editor. The editor used to mess with this dude, but she moved on while he didn't. Anywho, the main purpose of the movie was that the writer found out his book hit in Latin America, but sadly she turned his book into smut. So they're beefing about ideals for the creative nature of his books. After a while they decided to work together, come up with a dope book, and end up falling in love.
They have the sex and the movie could end on that note right.....WRONG!
We got to stretch the shyt out by having the ex take a picture of her laying down with him, just to make the writer jealous. Thus, 10 more minutes of fluff, when the movie should have ended on the note of both parties coming together and forget the guy from the past.
STOP WITH THIS TROPE!
