After awakening their memories, they realized that they had passed through the book. The two of them were each bound to a system and were forced to attack the regent and the prince. If they failed in the task, they would die directly. Xiao Nianzhu: Destiny is your fake rice cake, destiny is your Apache Chu Yaoan: You deserve eighteen coins for your destiny "Huh? So familiar. My best friend turns out to be you!" Until they saw their target Xiao Nianzhu: Are you saying that my target is an uncle in his forties? Chu Yao'an: And the target of my attack is actually a romantic and merciless rotten cucumber? The two decided to give up: "Whoever likes to do this task can do it, no matter if they take their lives." Then I thought: Hey, wait a minute, who said they must attack the current partner? We just need to find someone to take their place and marry him. As a result, the two started their "routine of cultivating gu". One day, Xiao Nianzhu looked at the handsome young man in front of her and suddenly realized: "No, you never said that the regent's son is so handsome!" Someone: "Hi, we meet again." On the other side, Chu Yaoan stared at the young man and said bluntly: "Do you want to be the prince?" The young man was stunned: "No..." "But I must marry the prince." The young man took a deep breath and looked firmly: "I'm sorry, brother, the crown prince's position must be mine."
