Don't Mess With the Little Sis! Master Jin Is Brutal and Crazy

A fictional country

A sweet, protective younger sister + an obsessive, ruthless older brother who spoils her

The little boy she casually brought home when she was six would become a part of her life forever.

When he was ten, his parents argued and abandoned him by the roadside. Each thought the other would take pity on him and bring him home, but in the end, she was the one who took him in and gave him a warm home.

When she was nineteen and taking the college entrance exam, a building contracted by her parents collapsed, killing twenty people. They were buried in debt, and all they could do was fight to survive.

Grateful to the Xu couple for their kindness, he set out to get justice for them, embarking on a path of no return.

Knowing what they had done to her brother, she secretly vowed to make them pay.

He risked his life, stepping into the trap himself.

By the time he was twenty-five, he had made a name for himself. His long-missing parents returned one after the other, claiming him as their son.

He used their influence to achieve his goal and win justice for the Xu family.

“Brother, are you going back to be their son?”

“Yes, but there's something I really want to do first.”

“What?”

“You. Come with me...”
