He's the Most Obedient [Book Transmigration]

Yu Jin'an transmigrated into a book he'd once confiscated from a student.

The young master of the Yu family in the book shares his name and surname. He's the most beautiful person in the Imperial Capital, delicate and pampered, with a sweet, gentle appearance, but a heart as poisonous as a snake's.

The young master was betrothed to the Empire's crown prince as a child, making him the envy of countless Omegas across the Empire.

But before their wedding, his dream fiancé was disfigured in an accident, his mental abilities damaged, and his intelligence reduced to that of a three-year-old.

The young master was desperate to break off the engagement, but pressure from his family's reputation forced him to marry into the imperial family.

After the wedding, he grew even more disgusted with his foolish husband. He beat and berated the crown prince, while openly cheating on him. The crown prince had already been abandoned by the royal family, and now his life became even more miserable.

One day, the crown prince's mind recovered, and those who had tormented him would pay for it.

His crown princess met the most horrific end of all...

Yu Jin'an shuddered. As an educator, he was very good at looking after children.

So the crown prince discovered that the wife who was supposed to beat and scold him instead stroked his head and gently coaxed him: "Good boy. Eat your food."

The wife who was supposed to join forces with outsiders to take his power instead shielded him from his power-hungry brothers, pretending to be fierce as she shouted, "Get out!"

His little wife had become so sweet. How was he supposed to resist?

P.S. 1v1, both are each other's first love, ABO, interstellar setting.

Theme: They choose each other, and make one another better.
