Modern overworked worker Jiang Li dies from overwork and transmigrates into a book, receiving the task of preventing villain Lu Shangxiao from turning dark. She originally intended to drug him to get close to Lu Shangxiao, but his second younger brother Lu Shanglin swapped the medicated wine, leading them to get married by a twist of fate. After marriage, the two went from mutual dislike to gradually developing feelings, and also unlocked the system's shared permissions, joining forces to confront the behind-the-scenes villains Bai Youyou and Tan Chen. The two played along to swap the R&D formula, and also planned a fake bankruptcy, with Lu Shanglin staging a fake death scheme to force Lu Shangxiao to break free from plot control and completely wake up. The villains' plot was exposed and they suffered the consequences, and Jiang Li also made her own choice between her lover and her mission.
