Lin Xiaoxia is an ordinary design student who unexpectedly gains the ability to transmigrate between different worlds. In each world, she must use her design talent to resolve complicated emotional entanglements in order to earn the chance to return to reality. From ancient palaces to modern cities, from fantasy kingdoms to future societies, she faces the pain of unrequited love, the hurt of betrayal by friends, and the barriers created by misunderstandings within families. Each time, she cleverly uses design to build bridges toward reconciliation, but as she completes her missions, she forms deep emotional bonds with key figures in each world that are difficult to let go of. Even more unexpected is that Lu Zechen, the System's guardian, has been quietly watching over her journey all along, and feelings gradually develop between them. However, as her missions progress, Lin Xiaoxia discovers that her transmigration was no accident, but part of a much larger conspiracy. She must complete every world's mission and unravel the mystery of her own origins, all while facing threats from within the System and interference from villains. As the truth gradually comes to light, Lin Xiaoxia must make a final choice: stay by the side of the one she loves, or continue shouldering her mission to travel between worlds?
