Wu Xiaoyu grew up in an orphanage. She has a gentle and timid personality, but unexpectedly inherited her mother's koi bloodline - anyone who is sincerely blessed by her will have three days of good luck. When she was eighteen years old, the wealthy Wu family came to visit her, claiming that she was the real daughter who was mistakenly carried away eighteen years ago. However, when she stepped into the door of the Wu family, what greeted her was not the warmth of family, but the sinister plot of the fake daughter Wu Xuewei and the cold questioning of the whole family.
"A wild girl who grew up in an orphanage is worthy of being the eldest daughter of the Wu family?"
"Looking at her timid look, how does she look like someone from our Wu family?"
Everyone thought Wu Xiaoyu was weak and could be bullied, but they didn't know that her koi ability was quietly awakening. When the fake daughter secretly stumbled, Wu Xiaoyu's inadvertent blessing made her opponent inexplicably unlucky; when her family tried to kick her out, the flowers and trees she took care of turned out to be priceless medicinal materials.
What is even more unexpected is that the legendary cold-blooded business emperor Gu Beichen actually saw through Wu Xiaoyu's specialness when they first met. "Your eyes are very special," he leaned down and whispered in her ear, "reminds me of some interesting things."
In this contest between real and fake daughters, Wu Xiaoyu discovered that his koi ability was far more than a simple blessing. And when the shocking conspiracy of the fake daughter gradually comes to light, everyone will face a cruel choice: Is it the luck brought by the koi carp or the true love deep in the human heart that can save this wealthy family that is about to collapse?
