In a childhood accident, Zheng Qingqing, the true heiress of the Yu family, was abducted by human traffickers while trying to save a little boy, and her parents tragically died in a car accident on their way to search for her. She ended up in a remote mountain village, was adopted by farmers, and became close friends with Yu Qianqian, a girl from the same village. Lu Tingzhi, the boy saved back then, never gave up searching for his lifesaving moonlight over the years, publishing missing person notices and detailing even the unique tattoo details on her body. Yu Qianqian happened to see the notice, filled with jealousy and greed, and behind Zheng Qingqing's back, she replicated the same tattoo, usurped her identity, and transformed overnight into the lifesaving benefactor that Lu Tingzhi had been bitterly searching for.
