Who knew that such an affable lass is a product of a family disappointment? Seine Antoine Cho, supposedly the heiress of M&G Real Estate, is now known as the whirlwind of grease and gasoline in a family obsessed with tradition. While her older brother, Arsène, went into medicine, a profession considered advantageous to the family's extensive real estate development business, Sen had other plans. Her passion couldn't be found in boardrooms and designs, but the sound of motors, the smell of burning rubber, and the excitement of a race.
Much to her parents' dismay, Sen stubbornly refused to take her place as heiress, choosing to chase her dreams on the racetrack instead. Her father saw a rebellious disappointment, while she saw a life lived on her own terms, even if it meant a constant battle against the expectations, and the considerable leverage of her family's wealth. The weight of the company, like a checkered flag, loomed in her future, a prize she didn't want, but one she might be forced to claim.
