I like the tension involve with a forced marriage scenario but really almost anything can provide that angst. I particularly enjoy humorous stories
I love when our dear couple find themselves stranded or kidnapped and must work together to outwit their kidnappers and free themselves from whatever strange situation they’ve found themselves in. They talk plainly,listen,formulate plans and inevitably find character traits previously hidden,but now greatly admired. Their previous misconceptions of the other tend to be erased and a newer,better understanding and appreciation dawn.
