Chapter 1

My wife and I decided to try IVF after years of struggling to conceive. Just before the embryo was created, I caught her swapping my sperm with her ex-boyfriend's.

I didn't say a word. I switched the sperm back and replaced her eggs with my ex-girlfriend's.

Twenty-five years later, my wife's ex-boyfriend showed up at our door, desperately trying to claim my son:

"My dear boy, I'm your real father!"

My son Noah and I had just returned home from an overseas medical cooperation project when we were greeted by an unexpected sight. Our living room was packed with distant relatives we rarely ever saw. The atmosphere was tense, as if a family council was in session.

At the center of it all, sitting on the couch with red-rimmed eyes, was Brandon White. My chronically absent "devoted wife," Yvonne Rivers, was comforting him in a sickeningly sweet voice.

I raised an eyebrow, set my suitcase aside, and turned to Yvonne. "What's the special occasion? Why such a crowd?"

Noah stood behind me, arms crossed, eyeing Brandon with disdain. He had already guessed this man's identity.

My mother-in-law sat in the main seat, her expression troubled and hesitant.

Before Yvonne could speak, Brandon lunged towards Noah, crying out, "My dear son, I'm your real father!"

Noah deftly sidestepped him, his face contorted with disgust as if Brandon were something foul. He took a step back, his voice ice-cold: "My father's name is Zane Gray."

That's my boy, always having my back.

I took Noah's hand, giving him a reassuring look, then swung my fist, connecting solidly with Brandon's face. The dull thud echoed through the living room.

"Don't go around claiming false relationships," I said, my voice frigid and my eyes sharp as knives.

Yvonne jumped up, rushing to Brandon's side with concern. She pointed at me, screaming, "Zane, have you lost your mind? How dare you hit Brandon!"

She raised her hand, about to slap me.

Quick as lightning, Noah stepped forward and slapped Yvonne instead.

"You dare to hit my dad?" Noah's voice wasn't loud, but it carried an undeniable authority.

Yvonne froze, shocked and furious. She raised her hand again, this time to hit Noah.

But Brandon grabbed her, putting on a show of fatherly concern. "Yvonne, don't! He's our son!"

His act of the doting father made me want to vomit.

Yvonne lowered her hand, glaring viciously at Noah. "If it weren't for your real father's sake, I'd teach you a lesson right now!"

Noah let out a cold laugh. "Hah, I'd like to see you try."

His piercing gaze was eerily reminiscent of my younger self.

I couldn't help but feel proud. This was indeed the son I had carefully raised!
