When Mark lost a birthday bet, he never imagined a simple haircut would change everything. Hidden beneath years of thick hair was a strange tattoo that no one, not even Mark, knew existed.

Mark leaned against the side of his truck, wiping sweat from his forehead with the back of his hand. It had been a long haul. Two states. Four deliveries. No sleep. And now this.

“I can’t believe I lost that bet,” he muttered.

“You believe it,” Trevor said, hopping out of his car with a grin. “You said you’d shave your head if I beat you at darts. I beat you. Fair and square.”

Mark groaned. “Yeah, yeah. Happy birthday to me.”

Trevor slapped him on the back. “This is what birthdays are for—humbling moments, big laughs, and terrible hair decisions.”

“More like terrible friends,” Mark said with a smirk.

Trevor wasn’t wrong. It was Mark’s 27th birthday, and he didn’t want a party or cake. He just wanted peace and quiet. But Trevor, his childhood friend from the shelter, had a way of dragging him into wild ideas. Elena, his girlfriend, always said Mark was “too soft-hearted for his own good.”

“You sure about this?” Mark asked, looking at the barbershop door.

Trevor shrugged. “You promised. Besides, it’s just hair. You’ll look tougher. More mysterious.”

Mark ran a hand through his thick brown hair. “I like my hair.”

“You’ll like your new look better,” Trevor grinned. “C’mon. Let’s get it over with.”

Inside the shop, the hum of clippers filled the air. It smelled like shampoo and talcum powder. The barber, a tall guy in his fifties with salt-and-pepper hair, gave Mark a nod.

“You the birthday boy?” the barber asked.

“Unfortunately,” Mark muttered.

“Buzz cut, right?” the barber asked.

“Yeah,” Trevor jumped in. “All off. Make him shine.”

Mark sighed and sat in the chair. The barber draped the cape over him.

Trevor handed him a cup of tea. “Drink up, buddy. You’ll need strength.”

Mark took a few sips. “Thanks, man.”

His eyes were heavy. The chair was warm. The buzzing of the clippers sounded like a lullaby. Before he could say another word, he dozed off.

“Hey… hey, man… wake up.”

Mark blinked. His neck hurt. His mouth felt dry. He looked up and saw the barber staring at him.

“What?” Mark mumbled.

The barber looked uneasy. “You didn’t tell me about the tattoo.”

Mark blinked again. “What tattoo?”

“The one on the back of your head. Real sharp lines. Like a barcode. What does it mean?”

Trevor chuckled from the corner. “Tattoo? He doesn’t have a tattoo.”

“I’m not kidding,” the barber said. “It’s right there.”

Mark sat up straighter. “There’s no way. I don’t have any tattoos.”

“I’ll show you,” the barber said. He picked up a hand mirror and held it so Mark could see the back of his head through the larger mirror on the wall.

Mark’s breath caught.

Clear as day, there it was. A black barcode. Perfect lines. Numbers and symbols underneath.

“What the…” Mark whispered.

Trevor leaned in. “Okay, that’s creepy.”

Mark turned to the barber. “Is it… real?”

“Looks real to me,” the barber said. “I’ve seen a lot of tattoos. This one’s not fresh, but it’s clean. Could be years old.”

Mark stared at it. “I’ve never seen this before. Never felt it either.”

Trevor frowned. “Dude. You’ve had that under your hair this whole time?”

“I don’t know,” Mark said. “I really don’t know.”

Silence fell over the room.

Mark stood up, suddenly cold. “I need to get out of here.”

Trevor followed him to the door. “You okay?”

“I don’t know,” Mark said again. “But I need to figure out what this is.”

And with that, he stepped into the fading light of the afternoon, questions racing through his mind.

Later that evening, Mark paced the floor of his apartment, phone in hand, heart still thumping hard in his chest. He couldn’t stop looking at the photo. That barcode tattoo—neat, black, bold—sat right on the back of his head like it had been there his whole life.

But it hadn’t. At least… he didn’t think it had.

He hit the call button.

“Trevor,” he said as soon as his friend picked up. “You need to get over here. Now. Bring Maya and Jose.”

Trevor yawned. “It’s late, man.”

“Just come,” Mark snapped. “I think this is serious.”

Trevor paused, then said, “Alright, alright. We’ll be there.”

Less than half an hour later, Mark’s small living room was full. Maya, sharp-eyed and always tapping on her laptop, had already started examining the photo. Jose leaned against the doorframe, calm as ever. Trevor was chewing a cold slice of pizza.

Mark held up his phone again. “This. This is what the barber saw. What I saw. I didn’t even know it was there.”

Maya zoomed in on the image. “It looks real.”

“It felt real,” Mark said. “What if it’s not just a tattoo? What if it’s a message?”

Trevor raised a brow. “Like… a message from who?”

Mark hesitated. “I don’t know. My parents? I mean, I was left at a shelter as a baby. No note. No name. Nothing.”

Jose stepped forward. “You think this could be a clue?”

Mark nodded. “I can’t stop thinking about it.”

Maya tilted her screen. “Hang on. Look at the numbers under the barcode. See this? Two dots… then a colon. That’s not just a random string. That looks like GPS coordinates.”

Trevor blinked. “Wait. Like, actual map coordinates?”

Maya was already typing. “Let’s find out.”

Everyone leaned in as she plugged the numbers into a mapping tool. A red pin appeared.

“It’s a spot in the woods,” Maya said. “Just a couple kilometers from here. Walking distance.”

Mark stared at the screen, heart pounding again. “I want to go.”

“Right now?” Jose asked.

“Yes,” Mark said. “I have to.”

Trevor scratched his head. “Well… if this turns into a creepy movie scene, I’m blaming you.”

Maya closed her laptop. “I’m in.”

Jose nodded. “Let’s go.”

The night air was cool and still. The path leading into the woods was dimly lit by the moon, but the GPS dot on Mark’s phone kept them on track. Every step crunched leaves and twigs beneath their feet.

They didn’t speak much. The woods felt like they were holding their breath.

Mark walked fast, phone in one hand, flashlight in the other. His thoughts were tangled. Could this really be something? A message? A piece of his past finally breaking through the silence?

“You alright, man?” Jose asked from behind.

Mark nodded. “I just… need to know what’s out there.”

After twenty minutes, they reached a small clearing. The air opened around them, thick with quiet.

“This is it,” Maya said, checking her phone. “Exact spot.”

The clearing looked ordinary. Wild grass. A few old tree stumps. Nothing out of place.

“Anything look strange?” Trevor asked.

Mark moved ahead, scanning the ground. Then he paused. “Here. The dirt’s loose.”

He dropped to his knees and pulled a small shovel from his backpack.

Trevor raised a brow. “You brought a shovel?”

“Comes with the job,” Mark muttered. “Never know when you’ll need to dig something out.”

He started scooping. The dirt came up fast and dry. The others stood around him, flashlights steady. Five minutes in, his shovel hit something hard.

Clunk.

Mark froze. He dug more carefully now, brushing away layers of dirt until a rusted metal box appeared. He stared at it for a moment.

Jose leaned closer. “What do you think it is?”

“I don’t know,” Mark whispered. “But it’s something.”

He lifted the box out of the ground and placed it on the grass. The group circled around. Mark’s hands hovered over the latch.

He took a deep breath and opened it. Inside was a folded note.

He opened the paper slowly, heart hammering. Before he could even read a word, Trevor snorted. Then, he laughed.

Not just a chuckle. A full belly laugh that echoed through the trees.

Mark looked up, confused.

“What?” he asked.

Trevor didn’t answer. He was laughing too hard to speak.

“Read it,” Jose said.

Mark read out loud:

“HAPPY BIRTHDAY! THIS IS A PRANK, BRO! DON’T FALL ASLEEP IN THE HAIRDRESSER’S CHAIR ANYMORE!”

Mark blinked. Next to the note sat a bottle of root beer. His favorite. A disposable razor. And a tiny blue toy truck, the kind he used to play with back at the shelter.

Mark stared at the items in silence. Then turned slowly toward Trevor.

“I got the idea weeks ago,” Trevor said, doubled over. “Maya helped with the coordinates. Jose kept the secret. The fake tattoo? That was my cousin Mel—she’s a makeup artist!”

Mark looked at them all. “You gave me something to drink at the barbershop.”

“Chamomile and melatonin,” Trevor said proudly. “Put you right out.”

Mark sat down on the grass, still holding the toy truck. His voice was quiet.

“I really thought I was gonna find something about my parents.”

Trevor’s smile faded. He walked over and sat beside him.

“I know, man. I’m sorry. I just… wanted to give you a memory. Something funny. Something real. We’ve been through so much.”

Jose nodded. “You’ve got people now. We might not be blood, but we’ve got your back.”

Mark stared at the bottle of root beer. Then he laughed—a deep, tired laugh. “You guys are the worst,” he said, grinning.

Trevor clapped him on the back. “Happy birthday, bro.”
