The Retired Young Mercenary Is Secretly a Billionaire Chapter 3: The Letter Keeper

The private jet taxied to a smooth halt on the secluded airstrip just outside Star Harbour. The sky had begun to darken into a dusty twilight, casting a soft orange hue over the glassy coastline and shimring city skyline in the distance. The door hissed open, steps extended.

Miles descended without a word.

Waiting at the bottom stood a sharply dressed man in his early thirties. Dark blazer over a turtleneck, black gloves, clean-cut beard, and sleek aviator shades pushed back into his slick hair.

He stepped forward with a courteous nod. "Mr. Miles? I’m Ethan—your driver."

Miles nodded faintly, eyes scanning the surroundings.

Ethan was the type who blended in with rich company — forr valet turned private chauffeur, quiet, trustworthy, trained to mind his own business. Hired through one of Monica’s usual channels, he had no idea who he was really serving. Just that his employer’s na opened doors that stayed shut for ordinary n.

"I’ve been told you prefer a quiet ride. The address is already in the system," Ethan said, opening the door to a sleek, obsidian-colored Bentley Flying Spur, its engine purring like a predator at rest. The interior slled of fresh leather and luxury.

Miles slid in without a word.

As they glided out of the airport gates and into the glowing streets of Port City, his gaze remained fixed outside. The city had grown since he last rembered it — taller buildings, cleaner roads, brighter lights — but the air still carried the scent of salt and rust from the harbor.

And as they turned into the quieter residential district marked on the old letter, ti began to slow.

Familiar houses — aged, modest, dignified — stood in long lines, so renovated, others preserved in fading charm. His fingers twitched as mories started pulling at his chest like the tide.

Then, he saw it.

The house.

Two stories, pale blue paint faded to almost white. White picket fence, slightly tilted to one side. It had been patched and painted over the years, but its bones were still the sa.

He stepped out slowly.

And walked up the steps.

He raised his hand to knock... but for a mont, it hovered — suspended in ti. Then, with a gentle thud, his knuckles tapped against the wood.

The door opened.

A girl—no, a young woman—stood there. Barefoot, in a pale lavender hoodie, loose dark hair falling across one shoulder. Her eyes, soft hazel flecked with amber, widened as they t his face.

Her beauty was the quiet kind — not loud or made-up, but calm, like morning light after rain. A warmth that didn’t try to impress. Her skin held the golden kiss of the sun, and freckles danced across the bridge of her nose.

She didn’t speak right away.

Her gaze swept over him slowly — the lean build, the guarded posture, the silence that wrapped around him like armor. The weight in his eyes, the stillness in his stance, the way he stood like soone used to leaving more than arriving.

But sothing in her heart stirred. Like eting a na that had lived too long on paper.

A flicker of realization passed across her face.

"...You’re Miles," she said, more a quiet confirmation than a question.

Then, softer, "Aren’t you?"

His lips parted, but he didn’t speak. He simply nodded.

"I’m April".

She stepped aside. "Co in."

The living room slled of old books and jasmine candles. Light music played softly from another room.

April watched him silently for a few monts before finally saying, "I knew you’d co soday."

Miles stood still, eyes sweeping across the house’s interior, vaguely familiar but touched by different hands now. She walked ahead, guiding him gently to the living room.

"You don’t know ," she said, sitting on the edge of the old couch. "But I’ve known you most of my life."

She gestured to the side table where a ceramic box sat. "Your mother... Elena... sends a letter here every year. On your birthday. She never gave up. Not once. Always wrote the sa ssage on the envelope— ’Please hand this to my son, if he ever returns.’"

Miles slowly took the letter from his pocket—the one he carried since the capital. Her eyes flicked to it.

"That one," she said, voice softer now, "never reached us. Three years ago, we waited, but nothing ca. I thought maybe... maybe you were back. That she finally found you. But then, the next year, the letter ca again."

She stood, walked to a nearby cabinet, and opened it. From it, she pulled a worn, tal box. She carried it over and placed it gently before him.

"It’s all here. Every single one. Since I was five."

Miles looked at her for the first ti, truly looked.

"My parents bought this house after your mother left. She left behind nothing but those letters. When the first one ca, addressed to a na we didn’t know, we were confused. My mom and dad kept them safe. Told I could be their guardian. So I waited every year with them... and started waiting for you, too."

She gave him a faint smile. "It’s silly, I know. But you beca part of my life without even being here."

He opened the box. Letter after letter, each in the sa delicate, hopeful handwriting.

He didn’t cry.

But sothing deeper happened — a crack, a shift — the weight of ghosts shifting in his chest.

April quietly stood and walked out of the room, giving him space.

And for the first ti in decades, Miles sat with the echoes of his past... not as Ghost, the killer, but as a son.

The room was quiet.

Miles sat with the box of letters on his lap, surrounded by dim lamp light and the faint scent of jasmine. The house, though changed, still breathed mories. His fingers moved over the paper edges — crisp, so yellowed, but all preserved. One envelope trembled slightly in his grasp. The handwriting. The way she always looped his na — Miles — like it mattered. Like she believed he’d see it soday.

He didn’t cry.

But sothing inside him did. A crack. A quiet breaking.

For all the lives he’d taken, the masks he’d worn, the nas he’d been called — this was the first ti he felt sothing real dig through the walls. Not guilt. Not regret. Just...Loss.

He leaned forward, pressing his knuckles to his lips. His breath shuddered. The box stayed open, and the letters whispered mories too heavy to speak.

Ti passed unnoticed.

Then ca the sound of gentle footsteps and the faint clink of ceramic.

April reappeared, holding two mugs.

"I didn’t know how you take it," she said softly, offering him one. "So... black. Like most lost n in stories drink it."

He managed the faintest of smiles — more shadow than shape — and took the cup. It ward his fingers, at least.

April settled back into the chair across from him, legs folded beneath her.

For a while, they just sat there. Then, quietly:

"Where were you all this ti?" she asked, voice curious, but kind. "I an, I don’t need details. I just... wondered."

Miles didn’t look up at first. Then he said, low, hoarse, almost unfamiliar with his own voice:

"Far. In places no child should end up in."

She didn’t interrupt.

"I didn’t rember much at first. Just fragnts. Then nas. Then I stopped using them. "He looked up, his eyes darker than the room. "But she... she never stopped."

April nodded. "She didn’t."

"My na wasn’t Miles for a long ti," he added, as if trying to convince himself it still was. "But... I never stopped feeling like soone was waiting."

"That was her," April said. "And, I guess... too."

A pause. The house creaked softly, like it rembered everything.

"My parents are on vacation," she said suddenly, lightening the mood a little. "I stayed behind — finals week. I’m in Star Harbor University. Lit major."

Miles raised a brow. "Books and old letters. Makes sense."

She smiled. "Guilty. And you?"

He sipped his coffee. "I... work for soone. Travel a lot. I’m not always... in one place."

April tilted her head. "Does that an you’re leaving again?"

He didn’t answer right away. "I just ca for the letter."

Another pause. His gaze dropped. "Didn’t expect all this."

"I’m glad you ca. ".

"I think she will be too."

Silence returned, but this ti it was gentler.

Eventually, Miles stood. "I should go."

April walked him to the door. "You’ll co again?"

He hesitated. "I don’t know what I am to this place anymore."

"You’re her son," she said. "That’s enough."

He stepped out into the night.

As the door closed behind him, Miles walked slowly to the Bentley. Ethan was waiting, standing beside it.

"Ready, sir?"

Miles nodded and got in.

The car glided away into the quiet streets.

Back in the car, as the city lights passed in blurs outside, Miles pulled out his phone. A file from Monica was waiting — flagged and marked CONFIDENTIAL: KELLER, ELENA.

He tapped it open.
