Rainbow knows that she is in love with Quibble Pants, but she doesn't know that she has to face the consequences of being saddled into an arranged marriage.
Soarin, on the other hoof, simply hasn't been ready for that kind of commitment. He never went out with mares, never kissed one-heck, he couldn't even talk to them!
Once they realize the compromise they have foisted on them, they decide to just deal with the challenges.
