After a night together in Mystic Falls, neither Klaus nor Hayley knows what they have. He wants her to stay, but she's unsure. As they navigate the uncertainty between them, every choice, every word, brings them closer or pushes them apart.

One night at the company anniversary with champagne and a bar equals accidental baby. Niklaus Mikaelson has worked too hard to let this ruin his career and relationship with his girlfriend who's currently in France, launching her new fashion line. So he makes a contract with Hayley. 1) After the baby is born she must leave it to him and never be seen or heard of again. 2) Don't fall in love. 3) Don't tell anyone about the contract or baby even after everything's over. Seems easy enough. Who's going to love an arrogant workaholic or a weird girl who always seems to fall too hard? But maybe 9 months is just enough time to break at least one rule? {Klayley AU}

At seventeen, Hayley Marshall is already a disaster, but she refuses to become a weapon. A triggered wolf burdened by recent, brutal trauma, she seeks to master the chaos within by dedicating herself to the rigid discipline of medical science. When her friend Stefan Salvatore brings her to Mystic Falls, she enters the toxic orbit of Klaus Mikaelson, the Original Hybrid defined by violence and currently blinded by an obsessive, unrequited fixation on Caroline Forbes. Hayley has no interest in fixing Klaus; she is too busy trying to suture the wounds of her own soul. Yet, her clinical competence, fierce resilience, and shocking lack of fear become an irresistible force against the Hurricane of Klaus's ego. As their worlds collide the scalpel meeting the fang-Klaus must confront the profound truth: the only person who can truly mend the chaos surrounding him is the very young woman who desperately wants nothing to do with his power. She is the unexpected Cure in the Chaos, and she might just break him open before she saves him.
