On the first day after transmigrating into a novel, Yan Mingxi receives a mission from a system: get close to Prince Yi, Xie Wanglan, the coldest man in the entire capital, and fill his affection meter through physical affection to rewrite her predetermined fate. Rumor has it that he keeps everyone at arm's length, but she insists on pursuing him—bringing him soup, blocking his doorway, and refusing to leave his residence. She pulls out every trick in the book. He may seem as cold as ice, but behind the scenes, he repeatedly makes exceptions for her. What began as a mission soon captures her heart as well. Yet, just when his affection reaches its maximum, she decides to run away. He corners her at the city gate and asks in a low voice, 'After using me, you think you can just leave?'
