Don't tell Soobin | Yeongyu / Beomjun

mark of sin ( and Yeonjun's mouth)

Beomgyu told himself it was a one-time thing.
A fluke. A heat-of-the-moment panic with a side of bad luck.

Except Yeonjun didn't act like it was one-time.
And worse—he followed through.

So when Beomgyu found himself pressed against Yeonjun's bedroom wall again the next day—barely breathing, hoodie collar pulled down, pulse racing under a certain someone's lips—
he didn't stop him.
Not when his mouth latched onto the curve of Beomgyu's neck.
Not when his teeth scraped.
Not even when it bruised.

"Y-Yeonjun—" Beomgyu gasped.

Yeonjun pulled back, satisfied. "You're mine now."

"EXCUSE ME?!"

"Visibly. Mine."

"You are so—"
Beomgyu nearly exploded.
But he still let him do it again.

The next morning, Soobin frowned across the table, squinting.
"Beomgyu, what's that on your neck?"

Beomgyu choked on his cereal. "What?! Nothing! A rash!! It's a—rash. I'm allergic. To soap. I mean, to life—"

Soobin leaned closer, suspicious.

From the hallway, Yeonjun strolled in, yawning. "Morning."

Beomgyu practically dove into his cereal bowl.

Yeonjun glanced at Beomgyu's neck, smirked, and sat across from them like he hadn't branded the poor boy hours ago.

Soobin narrowed his eyes. "Seriously, that looks like a—"

"A rash!" Beomgyu yelled. "Shut up and eat your toast."

Yeonjun sipped his coffee with so much smugness, Beomgyu wanted to die.
