This is a heartbreaking romance across class lines between Lin Nuanxi, a girl from an ordinary family, and Su Yuchen, heir to a business empire. An accidental meeting on a stormy night entwines the fates of the stubborn, resilient intern Xiao Xi and the cold, taciturn CEO from a wealthy family. When Lin Nuanxi proves her exceptional abilities and becomes Su Yuchen’s special assistant, the two gradually fall for each other amid business crises and their constant time together. But they face one obstacle after another: an arranged marriage between families, workplace schemes, and the gulf between their backgrounds. Su Yuchen is forced to accept the arranged marriage to protect Lin Nuanxi, and after losing her memory in a car accident, she forgets their love. When her memories return, the Su and Ye families join forces to suppress them, and Lin Nuanxi chooses to leave for another country. Two years later, she has become an internationally acclaimed photographer, while Su Yuchen has taken full control of his family’s business. They meet again at an exhibition, where the same black umbrella opens once more, bearing witness to a love among the wealthy about dignity, growth, and breaking free to become a butterfly. A car accident uncovers the shocking secret of Lin Nuanxi’s origins: she is no ordinary orphan, but the “perfect specimen X-1” from a genetic experiment conducted twenty years ago. To unravel the mystery, she joins forces with Su Yuchen, the cold heir to a wealthy family, Ye Liyue, the daughter of her nemesis, and Emily, a mysterious experimental subject, to fight the Omega Organization. As seven gene towers are activated, the four discover that behind the conspiracy lies the lost legacy of an interstellar civilization, and humanity’s future will depend on an evolutionary choice spanning light-years.
