To be the third (to cotinue the family name) and only son (also only child) of the rich Han family, ever since he was little Sang-Ah was ingrained with the motto 「A Successful Future comes from a Perfect Mate」 by his mother and raised with "Spartan-like" education. And due to his mother's harsh teachings about females Sang-Ah developed a serious aversion or trauma towards females. But one night during his age of 16, he's introduced to his fiance whom he has never met and Sang-Ah finally decides to leave his home. He leaves after making a deal with his mother that he'll find his own wife 'til he's 19 years old.
