After Dumping the Billionaire, the Genius Surgeon Makes a Powerful Comeback

Serena's POV:

I pushed open the heavy oak door to the study. The scent of dust, old paper, and leather hit me like a memory. Nothing had changed.

I didn't turn on the light. The moonlight filtering through the tall windows was enough. I walked to the large mahogany desk and sat in the leather chair. The cold surface sent a shiver through me.

There are also some medical-related books and scattered design drawings still on the desk.

I just sat there, in the quiet dark, as the last five years played out in my mind. Xavier's promises at the altar. My decision to give up my career for our family. The endless days of waiting, of being an afterthought.

I remembered my first pregnancy. I was so sick, and Xavier was on the phone, his voice impatient. "Serena, be reasonable," he'd said. "Savannah needs me right now. She's having a crisis with her final university project."

I remembered Mia's first birthday. I had a raging fever but still managed to decorate the entire house for her party. Xavier had returned from a European vacation with Savannah, and his gift to me was a silk scarf his sister had picked out.

Again and again, I had made excuses for him. He just cares deeply for his family. I had convinced myself to stay. Mia needs a complete home.

Tonight, I finally understood. I was never part of his "family." I was just a convenient, disposable part of the scenery.

I don't know how long I sat there before the sound of a car engine in the driveway broke the silence. Then, the front door opened, followed by a burst of noise. They were home.

I didn't turn on the light. I stood up and walked to the top of the stairs, ready to welcome them, wandering around my own home like a ghost.

From the entryway, Mia's voice, high and clear, rang out. "Auntie, you were amazing! The trophy is so shiny! You're so much more useful than Mommy. Mommy doesn't do anything but stay at home."

My heart seized, a physical clench in my chest as if an invisible hand had squeezed it shut. This was my daughter. The child I had carried for nine months.

Then came Savannah's voice, sickeningly sweet with its usual feigned innocence. "Mia, don't say that about your mother. She's done so much for this family. It's all my fault—I shouldn't have let you come back so late."

Xavier's low voice followed, soothing. "It's not your fault, Savannah. You earned this. And besides, Mia is just telling the truth."

A click, and the foyer light flooded the downstairs. The harsh brightness made me squint.

There they were, the three of them, a perfect picture of a happy family. I was the dark, extraneous smudge just outside the frame.

Xavier's eyes found me, His brow furrowed instantly. "Serena? What are you doing standing here in the dark? Who are you trying to scare?"

His tone wasn't concerned. It was accusatory.

Savannah rushed forward, her face a mask of perfect apology. "Sister, I'm so sorry, we're back so late. Are you angry? I didn't know today was..." She let her words trail off, a masterful performance of a slip of the tongue.

Mia peeked out from behind Xavier's legs. There was no guilt in her eyes, only a flicker of annoyance, as if I were a petulant child throwing a tantrum.

I looked at the three of them, at the way Xavier instinctively shielded Savannah and Mia, and a chill crawled up my spine.

It was laughable. I didn't say a word. I just pulled the corners of my mouth into a smile that felt more like a grimace.

I stood up, turned my back on them without a word, and walked back into the study.

"What kind of attitude is that, Serena!" Xavier's voice, sharp with irritation, followed me.

I ignored him and locked the study door. The click of the bolt was the most satisfying sound I had heard all night.

Through the thick wood, I heard Mia's voice rise in a wail. "Daddy, Mommy is scary... I don't want her! I want Auntie to be my mom!"

"I wish Auntie was my mom!"

The words were a poisoned dagger. They found my heart, twisted, and then broke off, leaving the blade inside.

I leaned against the door, my body sliding down until I was sitting on the cold floor. The tears finally came, hot and silent.

After they stopped, I wiped my face, stood up, and walked back to the desk.

I switched on the desk lamp. In its soft, focused glow, I pulled a single, clean sheet of A4 paper and a fountain pen from the deepest drawer.

I took a deep breath. At the top of the page, I wrote three words, my hand steady, my heart a quiet, frozen lake.

DIVORCE AGREEMENT.

In that moment, I drew a final, irrevocable line under the five years of my own foolishness.
