She was young and innocent.
He was married and happy.

When Catherine was on her way to take her late grandmother’s place in the Morrows’ Mansion, she had no intention of running into Dr. Rafael Morrow. She hadn't intended to pass out in the middle of nowhere, only to be found by him and have her emotions stirred up. She had no intention of conspiring with his wife and taking her place for one night - a night that would change her life forever.

She was only meant to bear his child, not fall in love with him.
He was never meant to find out.

When Catherine stumbled into his life, Dr Rafael Morrow wasn't ready to open the door to a forbidden affair, but life sometimes happens at the wrong time for all the right reasons.

Here is the translation, adapted into the explosive, high-stakes style of a bestselling American domestic thriller. The pacing is sharp, and the emotional transition from shock to cold vengeance is deeply amplified:

For five years, I honestly believed I was the happiest woman alive.

Until today. The day I came home early and stood frozen just outside the balcony, listening to his phone call.

"What? Shuying, you're pregnant?" Tingshen's voice was laced with a raw, unbridled euphoria I had never once heard before. "I knew getting rid of Jiang Wan's baby back then was the right move."

My knuckles turned stark white as I death-gripped the ultrasound report in my hand.

Qin Shuying. My absolute worst rival. They had been sleeping together.

"Tingshen, are you sure she won't find out?" Shuying's sickeningly sweet voice drifted through the phone's speaker, piercing my eardrums. "If Jiang Wan ever realizes you were the one who killed her baby, she's going to raise hell."

"Relax." Tingshen laughed, his tone dripping with the kind of casual contempt reserved for swatting a fly. "She's so clueless. She honestly believes it was her own failing body. The stupid bitch even cried and apologized to me. She'd never in a million years suspect I drugged her."

My nails drove so brutally into my palms that they broke the skin.

"Besides, I finally got my hands on her core design drafts. Consider them a welcome gift for our baby. As for her shares in the company..." He paused, savoring his own smugness. "She's about to sign them all over to me anyway. So what if her old man built an empire? It's all dropping right into my lap."

The world tilted violently on its axis.

I was carrying his child again.

Just five minutes ago, before I overheard this monstrous phone call, I had been acting like a giddy fool, planning the perfect way to surprise him with the news.

My trembling hand drifted down to my lower stomach. My chest cracked open, a visceral, violent tearing of my own heart. The baby I had desperately longed for and mourned... chemically aborted by their own father, all to keep his mistress happy.

My sweet babies, I thought, the devastating sorrow rapidly freezing into sheer, icy rage. Mommy is going to make them pay for every drop of blood.
