After Reincarnating as a Rich Heir, I Saved the Heroine’s Achilles’ Heel

[Transmigration into a Book / Dual Female Leads / Protection and Redemption + Mystery of Her Past]

Lu Yan transmigrated into a book.

The character he became wasn't even important enough to rank as the third male lead in the original story.

But he remembered one scene: on the eve of the college entrance exam, a girl was rushed to the emergency room. No one signed the paperwork or paid the fees, and treatment came too late.

The girl's name was Shen Zhi, the only younger sister of the female lead, Shen Qingyue.

In the book, the original Lu Yan happened to pass by the hospital that night. He took one look, then walked away.

Later, Shen Qingyue was reborn. She hunted down everyone who had stood by and done nothing back then, one by one. Lu Yan was among them.

On Lu Yan's third day after transmigrating into the book, that night arrived.

He went to the hospital and left his card at the nurses' station.

Shen Zhi survived.

From that day on, the original story went off track.

The people who were supposed to turn evil didn't, and the revenge still came, but the targets had changed.

Shen Qingyue treated him as her savior, yet never forgot one thing: this man was supposed to do nothing at all.

And Shen Zhi knew nothing.

All she knew was that she now had an older brother at home. He couldn't cook, and when he boiled the noodles to mush, he stubbornly claimed, "Even a dog wouldn't eat this." He got up in the middle of the night to bring her water, pretending he'd just woken up for a drink himself. He promised her that on her eighteenth birthday, he'd make her a bowl of longevity noodles with his own hands.

Her eighteenth birthday was almost here.

In the original story, she never lived to see it.
