xD How about we combine our ideas.I dont exactly think kidnapping someone and making them fall in love with you is very romantic but how about there is a war going on between humans and werewolves.My characters spots your character and his "senses" start to tingle.So instead of the kidnapping he transforms into a human and they fall in love that way.
Well....i'm not sure.I have never really made up one but how about the humans found out werewolves exist adn now they are hunting them down and trying to kill them.But your character is against it and falls in love with my character. Thats all I can think of. Unless you have something better in mind.
