When singer and American sweetheart Caroline Forbes and womanising up-and-coming actor Klaus Mikaelson meet on a flight they could never imagine the ensuing fireworks.

He took her as hostage because he needed leverage over her best friend, but nothing ever goes as planned when the baby vampire is everything but predictable and afraid of him. It's a road trip that Klaus will never forget. Au/Meme

The Mikaelson family had a saying. "Love beyond family is the greatest weakness. We do not feel and we do not care." It was a code he lived by. So why did he save the girl? Klaus / Caroline.

AU. Human. Niklaus Mikaelson, most bloodthirsty pirate of the seven seas. Caroline, the daughter to the Captain of an army ship. She challenges him, defies him and he wonders why he keeps her around. Then he looks at her and he knows why, because she is his and she makes him better. Then why does he hurt her? Why does he continually break her? KlausxCaroline

A/U Niklaus is a professional hitman waiting for the right moment to finally confront his father. Caroline is the girlfriend of a dangerous druglord whose partners are sick of his underhanded schemes. He never expected for her to be more than part of the job.

What was supposed to be "just one date" with the Original hybrid turned into a roller coaster of events which ultimately came down to one thing - Caroline Forbes making a choice that could either make or break her for, well...eternity. "Life sucked. After life was even worse..." (See Part 2: Uncharted Territory)

Human AU, where Klaus promises he's not a serial killer, and Caroline lets him in.

He eventually does take her to Rome, and they wander through the cobblestone streets, hand in hand. He offers her the world, and she takes it.
