"Inborn Pair" is about a resort president (also grandma’s boy) Ke Wei Xiang, who has the career he wants and is instead looking for his special someone. His grandma has betrothed Wei Xiang when he was still in the womb to the granddaughter of the man who saved her life, and grandma has been dreaming of the day her grandson can fulfill her promise. Wei Xiang is the reverse of the haughty, cold, and rude chaebol. He’s instead very considerate and kind, and he doesn’t have the heart to say no to his grandma’s lifelong dream. The heroine Song Yi Jie is a legal assistant at a law firm who is in the process of obtaining her lawyer’s license. She’s a righteous young woman who believes in standing up for justice and doesn’t care for love when she’s got a career to pursue. Episode 1 has Yi Jie and Wei Xiang meeting cute when she pretends to be the lover of a sleazy man so that his wife can obtain the evidence to force him sign divorce papers. On her way to the rendezvous, she chances upon a woman tearfully accusing Wei Xiang of breaking her heart (but in truth the woman is his daft subordinate). Wei Xiang thinks Yi Jie is a “Xiao San” (homewrecker) while Yi Jie mistakes Wei Xiang for a lothario who toys with women.
