After the demon king Xie Wuchang destroyed the world, he was accidentally reborn in another parallel time and space, returning to the time when he was still a bullied prince. He was horrified to discover that Bai Yueguang, who was forced to death by his own hands in his previous life and had never been able to get in his life, Shen Qingluan, the enemy's hostage, was actually sent to his palace as a "married man's wife" in this life. In order to make up for the overwhelming regret in his previous life, Xie Wuchang decided to change his fate against fate. He curbed his violence and took steps step by step, using the memories of his previous life to stir up troubles in the court and trample under his feet one by one those who had bullied him or plotted against Shen Qingluan. He protected Shen Qingluan under his wings, being extremely exclusive and partial, trying to raise this blue bird that should be flying high with endless pampering. However, Shen Qingluan, who originally thought he would fall into hell, gradually let go of his guard under the paranoid protection of the "monster" prince day after day, and joined hands with him to overcome the thorns in the road ahead, and jointly overturned this established tragic fate.
