It tells the story of a cross-class sadomasochism between a common girl Lin Nuanxi and a business empire heir Su Yuchen. An unexpected encounter on a rainy night intertwined the fates of the stubborn and tenacious intern Xiao Xi and the cold and taciturn CEO of a wealthy family. When Lin Nuanxi becomes Su Yuchen's special assistant with her extraordinary ability, the two gradually fall in love with each other during the business crisis and get along day and night. However, they face many obstacles such as family marriage, workplace conflicts and identity gaps. Su Yuchen was forced to accept the marriage in order to protect Lin Nuanxi, but she did not remember their feelings after losing her memory in a car accident. When her memory came back, Lin Nuanxi chose to leave home in the face of joint suppression by the Su family and the Ye family. Two years later, she transformed into an international photographer and Su Yuchen, who was completely in power, reunited at the exhibition venue. The black umbrella of that year was opened again to witness this rich love about dignity, growth and the emergence of a butterfly from a cocoon. A car accident revealed the shocking secret of Lin Nuanxi's life experience - she was no ordinary orphan, but the "perfect sample X-1" from a genetic experiment twenty years ago. In order to solve the mystery, she embarked on a journey against the Omega organization with the cold and wealthy heir Su Yuchen, the daughter of her old enemy Ye Liyue and the mysterious experimental subject Emily. With the activation of the seven gene towers, the four discovered that there was a lost legacy of interstellar civilization hidden behind this conspiracy, and the future of mankind will depend on an evolutionary decision spanning light years.
