🌟 Setting: Heaven High (and Somewhat Hell)

Nicholas adjusted his halo with the exhaustion of someone babysitting morally confused toddlers.

"Why am I even assigned to the Demon-Exchange Program?" he muttered.

Beside him, EJ — wearing crooked devil horns and looking aggressively confused at a pencil — poked his assignment paper.

"Nicholas, what's a 'con-sequence'?"

Nicholas stared.

"It's what happens when you do something wrong, EJ."

EJ blinked slowly, looking 10% confused and 90% unbothered.

"So... if I prank Yuma by switching his shampoo with whipped cream... will the con-sequence be funny?"

Nicholas clutched his head.

"This is why demons were banned from pranking angels!!"

Meanwhile at the other table, Jo and Yuma sat eating halo-shaped cookies, watching the mess unfold.

Yuma whispered, "Are they flirting or fighting?"

Jo, deadpan: "Yes."

😇 Scene 1: "Accidental" Touches

Nicholas tried valiantly to teach EJ basic decency for the fifteenth time that week.

"No setting things on fire to make 'dramatic entrances.'"

"No swapping the Angel Choir's robes with clown costumes."

"No kissing people just to cause 'emotional confusion.'"

EJ smirked and leaned closer.

"What if the emotional confusion was intentional?"

Nicholas flushed bright pink, wings twitching violently.

Jo whispered to Yuma, "I bet five bucks Nicholas combusts before midterm."

Yuma: "Make it ten."

😈 Scene 2: The Accidental Kiss Bet

EJ, bored out of his mind, slouched against Nicholas during flight practice.

Nicholas: stiff as a board.

"You're in my space," Nicholas hissed.

EJ grinned. "Sharing is caring."

Nicholas shoved him — except dummy devil EJ just grinned wider.

"Wanna make it a game?" EJ teased. "First one to kiss the other wins."

Nicholas glared, flustered. "Wins WHAT?!"

Yuma (from the sidelines): "Our eternal respect."

Jo (stuffing cookies in his mouth): "And bragging rights."

Nicholas: "I'M NOT PLAYING."

EJ, with a wink: "Too late, angel-boy."

🧨 Scene 3: The Great Prank War

Nicholas tried to focus on his "save-the-world" missions.

Instead:

His pen exploded glitter whenever he wrote "justice."

His halo turned pink every time he thought about EJ.

His homework kept mysteriously spelling "kiss me" across the margins.

Nicholas: "I AM A SCHOLAR AND A SERVANT OF GOODNESS."

EJ: "You're also blushing."

Nicholas: "NO I'M NOT."

Jo: "He's absolutely blushing."

Yuma: "Recording this for science."

🌟 Scene 4: The "Totally Normal" Study Date

Nicholas sat at the library table, notes neatly stacked.

EJ sprawled across from him, doodling little wings and horns on a paper airplane.

Nicholas, through gritted teeth:

"Are you even trying to learn?"

EJ smiled lazily.

"I'm learning that you look really pretty when you're mad."

Nicholas squeaked audibly.

Yuma clutched Jo's arm. "He's gonna pop like a stress balloon."

Jo: "Five more minutes."

🔥 Scene 5: Confession...ish

EJ leaned over, close enough Nicholas could count every stupid perfect eyelash.

"Hey," EJ said, voice low.

Nicholas couldn't breathe.

"Did you know demons have soulmates too?"

Nicholas tried to look unimpressed. Failed.

"So?"

EJ grinned. "Pretty sure I found mine."

Nicholas stuttered. "W-where?"

EJ tapped his finger gently against Nicholas's forehead.

"Right here. In the part of your brain that thinks I'm charming."

Nicholas made a noise only dogs could hear.

Jo whispered to Yuma: "You owe me ten bucks."

Yuma handed it over, grumbling.

🧺 Scene 6: The "Accidental" Kiss

It wasn't supposed to happen.

They were arguing over who ruined the mission logs (it was totally EJ).

Nicholas shoved him.

EJ tripped —
— Nicholas tried to catch him —
— and they crashed together —

— lips accidentally colliding.

Yuma dropped his juice box.

Jo started slow-clapping.

EJ pulled back, smirking.

"Looks like you lost, angel."

Nicholas, still pink: "...I think we both lost."

EJ winked. "Or we both won."

📜 Epilogue: Jo's New Group Chat Name

Jo renamed the group chat:

Nichojoo: Angel Falls for Dummy Devil™️

And Nicholas, finally accepting his fate, didn't even bother changing it.

The End.

(Because sometimes, the Devil's worst idea is actually the Angel's best decision.)
