1.
Christopher waited anxiously at the school gate, convinced beyond doubt that his dad would appear. The day had started perfectly, almost as if the world had conspired to line everything up just right: early morning exercises together, a shared breakfast full of laughter and clinking spoons, then the familiar walk to class where conversations wandered from serious matters to questions only children dared to ask —like whether dogs ever knew they were, in fact, dogs.
And then the ground shook.
The earth groaned, the walls trembled as if made of paper, and the air was split open by screams. Christopher clung to his teacher’s side, pressing his small frame into the safety of her arm, but deep down, he wasn’t afraid for long. He knew, with the unshakable faith only a child can hold, that his dad would come.
And he did.
Eddie’s arms wrapped around him like a fortress, melting away the terror in a single heartbeat. No matter how the world tilted or cracked, everything reset to “okay” the moment Dad held him close.
The car that picked them up wasn’t familiar, its hum strange against the chaos of the day. But then Dad said a name, and everything shifted.
That was the day Christopher met Buck.
He was tall —so tall that Christopher thought his hands might be big enough to hold up an entire building if they had to. He smiled in a way that lit the shadows in people’s hearts, the kind of smile that said, I see you, without needing words. And most importantly, he listened —not the way grown-ups usually listened, with half an ear and distracted nods, but with genuine care.
Christopher also noticed something else, something subtle but impossible to miss: in that car, Dad seemed… Different. His shoulders weren’t drawn as tight, his gaze less weighed down, as if Buck had quietly unlocked some hidden door in his chest and let the air flow in.
Dad breathes easier with Buck, Christopher thought with the absolute certainty of a child who knows what love looks like. We must never let him go.

After that, Buck began to appear more and more, as naturally as if he’d always been there.
Museums and aquariums turned into shared adventures. Dinners, sometimes elaborate, sometimes just pizza, stretched into long evenings of laughter.
What Christopher liked most was that Buck never treated him like a fragile glass ornament. He wasn’t “the kid” to be humored —he was someone worth talking to, listening to, joking with. Buck laughed with him when they fumbled through math problems, snored unapologetically on the couch during late-night movies, and stayed fully present even when words weren’t needed.
Over time, Christopher realized something about the men in his life: his dad watched over him like a soldier, always vigilant, ready to shield him from the world. Buck, though —Buck encouraged him to explore that world. He let him stumble, and then helped him laugh at the fall. He wasn’t there just to guard the path, but to walk it alongside him.
The strangest, most wonderful thing, however, was seeing the way his dad looked at Buck. As though Buck were some mysterious language Eddie had been trying to decipher his entire life. Every glance, every small gesture —pouring coffee without asking, offering a steadying touch— spoke volumes.
One afternoon, Christopher drew them. The three of them in a park, holding hands, smiling wide. He even added a dog, just in case Buck could finally convince Dad to get one. But what mattered most wasn’t the details. What mattered was clear: Buck wasn’t just visiting.
He was part of them now.

But life had its shadows.
When his mom died, Christopher sank into a silence so heavy it seemed to press on his chest. Dad cried quietly, in the dark, thinking Christopher didn’t notice. But Buck didn’t hide, and he didn’t push. He was simply there —with a notebook ready for doodles, a shoulder for leaning, a steady presence in the storm.
Then came the tsunami. Christopher still remembered the water pulling him under, his scream caught in his throat. He felt Buck’s hand slip away, terror gnawing at his heart —but then Buck found him again, clung to him with a grip that promised, I will never let you go.
Even when chaos swallowed them once more, Christopher never doubted. Buck would always come back.
When Dad was shot, the house filled with whispers too heavy for his ears. He saw Buck trembling, pale and stricken, as if the bullet had torn through him too. And when Dad finally returned, insisting he was fine, it was Buck who steadied him, who held him together even as Dad tried to push him away.
And when Dad thought keeping distance meant protection, when he shut doors thinking it was for their safety, Buck was the one who stayed. With Christopher. With Eddie. With both of them. Like family —because by then, that’s exactly what they were.

Yet Buck carried ghosts of his own.
One evening, he told Christopher about Daniel, the brother he lost before he ever had a chance to know him. Christopher saw it —the scar that didn’t show on skin but lived deep in Buck’s eyes.
Dad didn’t say much, he rarely did. But his silence was solid, the kind that meant, I’m here, I understand.
Then came the lawsuit. Christopher didn’t fully grasp what it meant, only that Buck was hurting and Dad’s frustration was nothing but fear in disguise —fear of losing him, fear of watching the ground give way again.
Until the lightning.
That day, Christopher thought the world was going dark for good.
He prayed the way he’d seen Bobby pray, clutching at words he didn’t fully know, begging for light. And when Buck finally opened his eyes, Christopher saw Dad’s face first: raw, stripped of all armor, carrying the look of a man who had almost lost everything.
In that instant, Christopher understood: what his dad felt for Buck wasn’t simple worry, wasn’t friendship alone. It was deeper, stronger, carved with both a beginning and an end that could only belong to one person.

Life, as it always did, carried on in chaos and color.
Buck was there for it all: flipping pancakes that sometimes burned, helping with homework, refereeing movie-night debates. He wasn’t a visitor anymore. He was woven into the home itself, like the walls, like the laughter, like the steady rhythm of everyday life.
With Buck, everything multiplied: more laughter, more calm, more joy. He wasn’t just an addition —he was the missing puzzle piece that completed the Diaz family picture. Without him, the edges frayed. With him, the picture was whole.
That night, while Dad and Buck bickered in the kitchen over what movie to put on, Christopher pretended to be absorbed in the TV. They thought he wasn’t paying attention. But he saw it —the softly way Dad touch Buck's shoulder or waist, the way Buck’s smile softened in a way reserved only for Dad.
No big declarations were needed.
Someday, Christopher knew, his dad would say it out loud. But until then, the truth was already clear to him:
Buck was his father too.
And together, they were family.
