"In reality, when two people are hot for each other, they get together fast, and then the complications come afterward."That looks really weird taken out of context. I'll explain.
Lost-Media (a Lost fan-site) had a link to this article: Chemistry: Pairing characters is tricky business about creating and maintaining chemistry on television shows.
It's a quick look at some of the lessons learned over the years from some of televisions most classic romances, with examples from Moonlighting, X-Files and Cheers to Gilmore Girls and Gray's Anatomy.
Of all the quotes in the story, that one really struck me, because it's what tends to happen in a lot of romance novels. It's pretty much a partial definition of a single-title romance novel. Just add the "fall in love" part, "overcome those complications" part, and the "live happily ever after" part.
