What is the use of getting married if you know that you are not gonna be faithful to one woman? I'd rather remain single all my life. ... Jillian Patrick’s everyday life was smooth sailing until she encountered the naughty twin girls. “Mom!” Her life got turned upside down with that single nightmarish word. “I am not your Mom. And I don't like kids!” She sobbed. Facing many trials and tribulations against the mischievous devil twins, Jillian eventually succeeded in escaping from them. Alas…Fate had some other plans in store for her in the form of Brayden Lawrence. Despite coming from the wealthy and prestigious Lawrence family, Brayden was allergic to the word “responsibility.” Because of that, he travelled out of the country, leaving his elder brother to handle the family's business. But now that brother is dead. Upon Brayden’s return, an even more shocking news awaited him. He was now responsible for his brother’s entire fortune and his twin girls. Fortune was one thing, but he was absolutely not ready to become a father! “If I wanted children, why would I have broken up with my ex-girlfriends then!?” The only solution to win his freedom back was to hire a babysitter. Seeing how the girls were already fond of Jillian, he proposed to her a deal. Jillian couldn't resist the drooling offer and readily agreed despite not liking children. As their paths now became one through this contract, how would taking care of the six-year-old twins change their lives? Will this contract make them come closer or put them deeper into a web of dangerous conspiracies?
