Bro, I Swear I Didn't Mean to Sleep with Your Son

Cui Zhao transmigrates into another world and gets bound to a romance System, which insists he win over the Son of Heaven's Destiny.

On the surface, Cui Zhao plays along. In truth, he diligently pursues his career, relying on quest rewards, and finally helps his sworn brother seize a vast territory amid the chaos of war.

But the emperor barely has time to settle into his throne before overwork claims his life.

Cui Zhao is appointed the chief regent and his good brother clasps his hand, entrusting him with a final request: "I entrust this realm, and my young son, to you. If you wish to take the throne for yourself, you may do so."

Cui Zhao looks at the young emperor, who keeps avoiding his gaze, and feels his head about to split.

That damn System switches targets seamlessly. The late emperor has barely died before it binds itself to the new emperor.

Cui Zhao grits his teeth and carries out the quests, but all he wants is to be a loyal minister who gives everything for his country and raises this little wolf cub... no, His Majesty, into a wise ruler.

He pacifies the lands for His Majesty and puts the court in order.

He shields the young emperor, blocking every open attack and hidden threat.

Until one night, during a palace coup, he protects the emperor with his life and collapses from exhaustion.

When he wakes, the young emperor is leaning over his bedside, his robes loose and his gaze dark. There is no trace of his former timidity.

[Congratulations! Your target's affection is about to reach the maximum!]

Li Yan presses him into the brocade quilt, and only one thought remains in Cui Zhao's mind:

Your Majesty! Brother Luo!

I have wronged you, but I never meant to sleep with your son!

Note: Cui Zhao and the late emperor truly shared only a brotherly bond.

Cui Zhao and Li Yan are eight years apart.
