A spoiled high-society heiress, Si, has always wanted to become the president of the family company. But her parents choose to give the position to her younger sister instead, because Si—as the eldest daughter—is selfish, impulsive, and spends hundreds of millions without a second thought. Then the family business runs into trouble and urgently needs to renew the lease on a prime piece of land. But no one has been able to negotiate a deal. That is, until Klaokawi, the owner of the valuable property—a simple country man who loves wearing fertilizer-brand shirts and living a rural lifestyle—steps in with an unexpected offer: Si must marry him in exchange for the lease agreement she desperately needs. And so begins a strange and complicated relationship between two people whose lifestyles, values, and worlds couldn't be more different.
