Counterattack Against Palace Changes at the Beginning

My name is Qin Zhen, and I am an ordinary citizen. I passed out while watching Paradise at home I traveled through time in the blink of an eye, and the good news is that I traveled through time and became the male protagonist of a cool novel! I originally liked Her Royal Highness the Crown Princess. The bad news is that the princess is the original sister-in-law. What you dare not do, then let me do it! Your Highness the Crown Princess, you don't want the Crown Prince to know either, right? This novel and its characters are purely fictitious. Any similarity is purely coincidental and should not be imitated.
