Cassius Fenrich must complete the Three Sacred Rules if he wants to inherit his grandfather's company. First, he must marry a woman. Second, they must produce an heir. Third, they have to live in his grandfather's childhood house, about two hours away from the nearest town. In a month, he fulfilled the first two, because, of course, he didn’t wear a condom while drunkenly having a one night stand with a stranger. Said stranger is Alice Harrison, a waitress and house-cleaning service provider with debts and a mother suffering cancer. Unfortunately, studying Criminology doesn’t make her money, but faking to be pregnant does. United under a marriage contract, they embark on a new chapter of their life, all the while trying to survive the crazy neighbors next door. Which is proven to be impossible, because – “I’ve seen serial killers’ footage and they act just like that. Trust me, either they should be executed on the chair, or they should be imprisoned in a mental hospital.” “No. They must be my grandfather's men, sent to spy us to make sure our marriage is not fake one.” Although both aren't always on the same page, they agree on one thing. They have to act 24/7 like a true married couple in love for Case to inherit the company, and for Alice to get the divorce money a year later. But, can they really put up the act? Or will they slowly fall in love? What will Case do when he finds out that Alice isn’t really pregnant? Better yet, what if she really is pregnant?
