Iris, a young woman with psychic powers, is pushed into a desperate situation when she is attacked by evil spirits and betrayed by her greedy stepmother, who drugs her to sell her off. In the chaos, she has a one-night stand with Declan, a brilliant detective from a wealthy family, and ends up pregnant with twins. To protect the children, the two sign an agreement and enter into a contract marriage. With her extraordinary ability to see vengeful spirits, Iris becomes Declan’s invaluable partner in solving crimes, and together they crack multiple shocking unsolved cases. When the mystery of her birth is finally revealed, her father— a top business tycoon—publicly announces at their grand wedding that she is the sole true heiress of the family. The greedy adoptive family is completely cast out, and Iris ultimately gains both profound love and justice.
