Gold kingdom and water kingdom

"Once upon a time, two kingdoms, one rich in gold, the other rich in water, shared a border. The two nations were always fighting until an agreement was struck: the most beautiful girl in the gold kingdom would marry the smartest man in the water kingdom, binding the two nations together. However, both sides tried to renege on the deal by sending animals instead! Sarah, a low-level princess, is selected to wed the man from the water kingdom, but is sent a puppy in place of a groom! Meanwhile, the candidate from the water kingdom, Naranbayar, is saddled with a kitten!"--Provided by publisher.
