One day when I was working as a low-ranking civil servant in a hopeless imperial palace department, I realized that I had reincarnated in a novel.“Oh my god, the villain is about to start a war, right? If a war breaks out, people like me will be the first to die!”An imminent war as per the original setting.If I want to live, I must first save the crown prince!To save the crown prince who dies first in the original story, I leaked the original’s information to catch the villains.Suddenly, I became the youngest minister.I didn’t really mean to get ahead, but there’s nothing wrong with that!Let’s just catch the villain.* * *It’s a lot of fun to ab*se the villains, and the taste of power is also very sweet.However…“His Highness the Crown Prince has a great sense of responsibility, but since he has nowhere to focus, he may want to run away sometimes.”The strange new intern is talking nonsense.No, how did I save the prince!“What? Run awaaaay?”With a glint in my eyes, I said grimly.“If His Highness runs away… I will personally chase him to the end of the continent. I will somehow drag him by the collar, stick tight next to him, and keep an eye on him.”Hmm?But intern, why are you shaking? Why are your ears red?
