Third, Rain likes to stay away from men but she didn't knew that her life is gonna take a twisted turn. Damien Carson, a thirty-nine years old successful businessman, handsome but rude and grumpy, is best friend and has a co-company 'C&S' with Rain Smith's father Ethan Smith. Damien never saw Rain more than his best friend's daughter but as she grew up Damien finds Rain's intelligence, determination and strong persona admirable but nothing more than that... Or there's something else? But Damien will find out soon enough when Rain is going to be his everyone and everything at once. "Because, we were born to break the rule"
