Not to be an ass, but they are much the same as any other genre.
1. A main character who seems real and is someone we can identify with and want to see reach their goals. (On rare occasions you might succeed with the opposite: a main character we loathe so much we want to see them get what's coming to them.)
2. A believable dilemma/situation/person/thing that is blocking your MC from achieving their goal(s).
3. Consequences for the MC not achieving their goal. (Usually referred to as "high stakes" because it is best when it is something that seems like it will be earth shattering. Sometimes though it may be a simple as not getting to the rock concert in time to see one's all-time favorite band.)
4. Complications arising from the MC's attempts to overcome the complications preventing him/her from achieving their goal. (Usually things get worse - way worse - before they get better.
5. Butt smex. HAH! Kidding. That's SP's line. So, an end to the story which follows the middle which follows the beginning.
The romance and candle lit dinner that turns into hot sex in the back yard. Or the rain drenched walk that turns into hot sex in the pool shed. Or meeting an ex-boyfriend that leads to a fight that turns into really hot make-up sex in the restaurant coat closet is all just details that come after the previously mentioned elements.
But then. I'm new to this side of things. I could be wrong.
