A-level mission executive, Dai Jiunian, the dream of 900 million girls. As the "star" of the 21st century who stood on the execution chain and overlooked everyone, he was bound to devote himself to the task of executing the most difficult tasks of the year. He came to a different world and became the arrogant little princess of the all-powerful... King? (Dai Jiunian thought in his heart: Don't I want to lose face?) In that world, there is their passionate youth, their youthful excitement, and the regrets of those years gone by are also buried. I will remember your voice even in the hopeless time and space in the future!
