My Useless Sweetheart Says He's Reborn

Luo Kun always thought her fake younger brother, who devoted himself entirely to academics, would become a scientist abroad and keep at it until he won a Nobel Prize.

She never expected him to return home one day with one piece of bad news after another, all beyond what he was capable of handling.

Jiang Yuyang: "My big brother cheated on you."

Jiang Yuyang: "My big brother wants to take your shares."

Jiang Yuyang: "My big brother even wants to keep you cooped up at home to have his children!"

Luo Kun: "I know. I don't care, and I'm prepared. He won't succeed."

But...

Jiang Yuyang: "My big brother wants to bully me too QWQ"

Luo Kun: "Enough is enough. Let's take him down!"

Luo Kun: "Wait, how do you know all this?"

Jiang Yuyang: "Well, you might not believe this, but I've actually been reborn..."

Only before he died did Jiang Yuyang realize his big brother was a ruthless man who showed no mercy and left no one standing. Unfortunately, by then it was too late, and he couldn't do anything.

When he opened his eyes, he realized he had returned to eight years earlier.

He swore to protect his delicate and timid fake older sister, but only later did he realize that he was the naive sweetheart who'd latched onto a powerful backer.

A wealthy family's bitter feuds, wall-to-wall melodrama. You may want to bring your own lightning rod.

#The knight is buying a Ferghana horse, while the princess over there is already max level#

That's more or less the idea.
