The story takes place in Texas, USA. The established Reed Group's core businesses are energy and real estate. Twenty years ago, babies were switched at birth. When the DNA results are revealed, Kimberly—raised for twenty years—is found not to be a blood relative. The true heiress, Belle, is brought back into the wealthy family. Having grown up at the bottom of society, she is naive and easily deceived. The clear-eyed Kimberly watches her stumble into pitfall after pitfall, internally mocking her for being too naive, yet is forced to step in and help her fight the hostile Porter family. In the end, feelings develop between the two, and they end up living together.
