Yeah the shapeshifter prince and the elven princess have to get to know eachother and they just keep butting heads until they start to fall in love... Oh and then like the princess's best friend steals her away at the wedding and holds her against her will in the forest and the shapeshifter prince should come and save her. ^^ sound cool?
How about an arranged marriage between the elves and the shapefshifters prince and princess. ^^ they don't like eachother for the longest time and then slowly fall in love with eachother
