Probability of paternity: 0.00%.
Santiago remained frozen on the living room sofa, breathing heavily as if the air itself had become too heavy to inhale. From the bedroom came Mariana’s cheerful laughter while she changed the baby’s diaper. For eight years that laughter had been the sweetest sound he knew.
Now it had become unbearable.
It sounded like mockery.
Like deception.
Like the cruelest betrayal he could ever imagine.
How long had she been lying to him? Who was the child’s real father? A handsome coworker? The neighbor who smiled at her a little too warmly every morning?
The questions poisoned his thoughts. Anger, disgust, grief, and confusion collided inside him until they became one overwhelming storm.
He couldn’t bring himself to confront her.
For five endless days he wandered through his own home like a ghost. He left for work before sunrise and returned long after dark, doing everything he could to avoid meeting her eyes.
Mariana immediately sensed that something was terribly wrong. She gently asked whether he was exhausted or overwhelmed, but he answered only with brief, distant replies that left no room for conversation.
Then Sunday arrived, bringing another painful test.
Her mother, Doña Carmen, had organized a family barbecue at her house in the southern part of the city to celebrate the baby’s birth. Music played across the backyard, bottles of beer were passed from hand to hand, relatives laughed together, and everyone admired the newest member of the family.
To Santiago, however, it felt less like a celebration and more like walking toward his own execution.
As Doña Carmen cradled the newborn in her arms, she smiled lovingly before making a casual remark that instantly sent a chill through Santiago’s entire body.
“My goodness, he’s so fair-skinned,” she said with a puzzled smile. “And look at that blond hair… I wonder who he inherited that from, Mariana? After all, both you and Santiago have much darker features.”

Вот продолжение в том же стиле — с естественным английским языком, высокой уникальностью, сохранением объема и драматического напряжения.
An uncomfortable silence settled over the patio. It lasted only a couple of seconds before Santiago’s uncles tried to lighten the mood with awkward jokes about the milkman.
For everyone else, it was a passing moment.
For Santiago, those two seconds felt like a lifetime of public humiliation.
Mariana forced a nervous smile.
“Maybe he takes after someone on my father’s side of the family,” she said softly. “Genetics can surprise you sometimes.”
Those simple words shattered the last fragile piece of Santiago’s self-control.
He wanted to flip the barbecue onto the ground, smash every bottle in sight, and scream the truth for the entire family to hear—that the baby wasn’t his.
Instead, he remained silent, swallowing every ounce of rage and heartbreak.
There was no longer any way to pretend he hadn’t seen the truth.
The explosion was only a matter of time.
By Tuesday evening, their house had fallen into an oppressive silence. Mariana sat peacefully on the sofa, folding tiny baby clothes with a calmness that, to Santiago, looked like the ultimate act of hypocrisy.
“Mariana.”
His voice echoed from the hallway.
Cold.
Flat.
Almost unrecognizable.
“We need to talk. I can’t keep pretending anymore.”
Her hands froze instantly. One glance at his face was enough to tell her that something terrible had happened.
“What is it?” she whispered. “You’re frightening me…”
Santiago walked toward her, his fists clenched so tightly that his knuckles turned white.
“Three years ago,” he said, his voice trembling with restrained fury, “I had a vasectomy.”
The tiny baby onesie slipped from Mariana’s fingers and landed silently on the floor.
The color drained from her face.

“What…?”
“You heard me!” he shouted. “After we lost our third baby, I couldn’t stand watching you destroy yourself anymore. I paid for the procedure in cash and never told you. But that means one thing, Mariana…”
His voice cracked.
“That child cannot be mine.”
Mariana’s entire body began to shake.
“No… that’s impossible.”
“I ordered a DNA test!” he interrupted, throwing his phone onto the couch. “I stole one of the baby’s pacifiers and sent it to a lab. The results came back with zero percent probability of paternity.”
His eyes burned with pain.
“So tell me the truth.”
“Who did you sleep with?”
Mariana let out a cry so full of agony that it echoed through the house before collapsing into uncontrollable sobs.
It wasn’t the crying of a guilty woman.
It was the heartbreaking scream of someone whose soul had just been ripped apart.
“I never betrayed you!” she cried desperately. “I swear on our son’s life—I have never been with another man!”
“Then explain it!” Santiago shouted before his strength abandoned him. He dropped to his knees, his entire body trembling.
