The Tyrant I Have to Win Over Is the Younger Brother I Had Before I Transmigrated into a Book

[The premise will stay the same, but the younger brother might become an older brother]

Ming Yu transmigrated into a book.

Her mission was to keep the plot on track by buying the male lead and tormenting and humiliating him, while also doing her best to reform him so he wouldn't grow up to become a cruel, bloodthirsty tyrant who slaughtered the people.

The mission was so contradictory it was a little... messed up.

But aside from the fact that tormenting the male lead was difficult for honest, mild-mannered Ming Yu, the rest didn't pose much of a problem.

Because the moment she saw the male lead, she realized he had transmigrated too.

And he was the younger brother she had depended on before she transmigrated.

Even when their parents were alive, her younger brother had always taken care of her.

After their parents died when they were young, they became each other's closest companions and relied on each other more than anyone else in the world.

Now that they had transmigrated to another world, Ming Yu still spoke openly with him about how to follow the plot from here on.

Whenever Ming Yu struggled with the idea of bullying him, her younger brother would reassure her that it was fine and tell her to go ahead without worrying.

When she couldn't bring herself to be cruel, he would guide her foot with his hand and teach her to step on his hand. He would take her hand and show her how to pinch his waist. In the dead of night, he would come to her room, take her hand from behind, and teach her how to whip someone...

He was the younger brother closest to her, the one who treated her best.

Ming Yu thought they would surely finish their mission soon and go home together!

Yin Heyue never told Ming Yu...

When he learned their parents were dead, when he learned that no one irrelevant would ever again wedge themselves between him and her, when she sobbed in his arms, barely able to breathe...

He had almost laughed out loud.

Go home?

Why would they go home?

From now on,

he would possess her openly and rightfully.

A gentle, sunny big sister x a mad-dog, crazed tyrant little brother

The plot begins after they transmigrate into a book, when they are no longer related by blood
