- Description from novelbuddy

Lin Yin was an unfortunate girl who lived in the slums for eighteen years because of mistaken identities at birth.

Even though she was brought back to live with her real parents, there was no place for her amongst them.

She was constantly bullied and scolded for no reason; her own biological parents would leave her in the dirt just because Su Fei shed a tear.

Swindled, and betrayed the very person she fell in love with, she was finally going to escape her dark life when she realized that it was all a setup — that she was just a clown.

She dragged her poisoned body as she tried to escape, but she was killed regardless at the loud crack of a gunshot.

Her departed spirit watched as her biological parents coldly said, “She has never been our daughter. Burn her, throw her into the dirt — you can do whatever you like.”

As the guest left, a man stood sighing with sympathy. “Take her to a funeral home. Let’s hope that in her next life, she can live for herself and not suffer so much grief.”

How laughable it was that she had lived for so long, but a stranger turned out to be the one who gave her a proper funeral!

Soon, Lin Yin lost consciousness, and woke up to find that she had gone back in time, to the first year after she returned to the Su family!

This time, she decided to live for herself without compromise! Still, just as she thought she would have to do this alone, she never imagined that she would be reunited with three brothers, although they never showed up in her last life!

They were Mu Heng, the magnate, Mu Qing, the prodigious doctor, and Mu Ran, the heartthrob and movie star!

In her last life, she gave her heart to the wrong people and suffered a tragic end, but in this life, her brothers were pampering her to death! Mu Heng: She’s my sister! I’ll protect her!

Mu Qing: Who dares bully my sister! Mu Ran: She’s my sister! I’ll spoil her!

Lu Ming: She’s my wife! I’ll watch over her! Mu Heng, Mu Qing, and Mu Ran: Get out!
