At Bangkok International University, the Faculty of Business was notorious for two things:

Sky don’t walk into classrooms. He arrived, always loud, and dramatic. He was the kind of student who made professors sigh and classmates laugh. Sat on desks instead of chairs, added unnecessary commentary to presentations, and referred to group projects as "team-building trauma."

"Move it, minions. The star has arrived!" Sky announced as he waltzed into the room like he was stepping onto a runway rather than into a Business Statistics lecture. He had one Airpod in, sunglasses perched dramatically in his hair despite being indoors, and an iced matcha latte in his hand.

Across the room, Nani Hirunkit didn’t even look up from his notebook. While the class buzzed like an overly caffeinated beehive, he sat in the corner seat by the window, the soft breeze ruffling his black hair, headphones snug over his ears.

And Sky being Sky.. he doesn’t care.

Just like always.. the first thing he did, was head straight to the back corner, pausing briefly by Nani's seat, Sky’s favorite target.

He leaned over Nani’s desk, resting his chin on his arms. "Good morning, sunshine."

Nani didn’t even blink. "You’re breathing too close."

Sky grinned wider. "You really need to get laid or lightened up, whichever comes first."

"And out of these two.. I vote for you disappearance."

"Now, now.." Sky tsked.

"Is that how you talk to your class rival? Your academic nemesis? Your one true intellectual enemy?"

"We’re not rivals. You just keep copying my assignments."

Sky plopped into the seat in front of him, turning around to face him like a kid desperate for attention. "You know, if you stared at people the way you stare at your notebook, you might actually make friends."

"I have friends." Nani said, flatly.

"Name one who’s not a fictional character or a plushie."

Nani glanced at him. "At least.. they don't speak nonsense all the time?"

Sky clutched his chest, fake-offended. "He’s mean to me again. This is abuse."

"File a complaint.. To someone who cares."

"You care though. My daily attention is the only reason you haven’t dropped out."

"You are the reason I think about it weekly." 

Their classmates were used to this. Sky provoking. Nani deflecting. They were like a storm cloud and a firecracker.. never blending, always clashing. But it was hard to tell who started it and who secretly enjoyed it more.

What no one knew, though, was that beneath Nani’s straight face and sarcastic walls..  He has a soft spot for someone.. a crush.

Not on Sky.

Definitely not.

He liked someone else. A soft-voiced student from the next section who always smiled, always said hi, and once helped him pick up his books after he dropped them. That tiny moment had spiraled into a crush Nani was too embarrassed to admit even to himself.

And after weeks of second-guessing and deleting texts, he did something very un-Nani.

He wrote a letter.

A real one. With pen. And emotions.. It was painfully awkward and cheesy. He nearly died re-reading it, but it was honest. So, he folded it into a neat square and planned to drop it into their locker the next morning.

Which he did.

Except.. in his rush and nerves..

He miscounted the rows.

He dropped it into locker #54.

Sky Wongravee’s locker.

And the next day, karma came for him.. loudly and unapologetically.

"OH? What is this?" Sky’s voice rang through the classroom, clear and gleeful.

"Is this a love letter? Delivered to my locker? Is someone finally admitting they can’t resist my charm?"

Nani froze, mid-turn, coffee in hand, eyes widening in horror.

This is too much of a coincidence.

No. No. NO..

Sky peeled it open like unwrapping a birthday present. "Listen to this.. Your smile makes the worst days better, like a playlist that never skips a song."

"Oh MY GOD. This is so sweet." He gasped.

"No way.. Someone actually wrote you a confession letter?" Mark said from behind.

Nani hunged his head low, heart in his throat, coffee forgotten.

"Sometimes I think the universe put you in the same hallway just to mess with my heart. WHO WROTE THIS? I demand answers!" Sky’s grin grew wider with every second.

Laughter bubbled around the room. Phones were already out. Someone whispered.. "Who even write a letter at this age?"

Another said. "Did someone seriously confess to Sky?"

Sky peeked at the letter again, and then he looked up, slowly.. looking at Nani dead in the eyes.

He saw the name. Of course he did.

But he didn’t say a word.

Instead, he smirked.

Not just any smirk. The kind that promised trouble. The kind that knew something no one else in the room did.

"Oh, mystery lover.." Sky said playfully, twirling the letter between his fingers.

"I don’t know who you are.. but this? This is adorable."

He turned his head just enough to glance at Nani again, this time with a tilt of his head and a look that practically screamed.. I know.

Nani’s eye twitched. He immediately looked away.

Sky chuckled, loving every second of this.

He folded the note carefully, tucking it into his back pocket like a precious little secret, and head back to his chair with a grin stretching ear to ear.

"Guess I have a secret admirer now." He said casually to the class.

Nani was dying. Slowly. Quietly. On the inside.

And the worst part? Sky didn’t out him.

He didn’t have to. He was enjoying it way too much.

Earlier in the locker room.

Sky was late.. As always.

He strolled into the university locker hallway with his usual swagger, earbuds in, hair a mess in that artfully careless way, sipping on bubble tea.

As he popped his locker open, something slipped out and fluttered to the ground.

A paper.. No a letter.

Soft, folded, and neat. Cream-colored paper with frickin’ a heart doodled on the corner.

"Oh?" He murmured, crouching to pick it up.

Then he glanced around. No one seemed to be watching.

With a dramatic roll of his eyes and a smirk already forming, he unfolded it, preparing for a laugh.. Maybe a prank.

But then he read it.

"You probably don’t even notice me when I look at you... But your laugh sticks with me. And when you’re not here, the day feels dull. Maybe it’s stupid. Maybe I’m stupid. But I like you. A lot."

Sky blinked. His smirk twitched but didn’t disappear. The letter was cheesy. Like, painfully so.. Like straight out of a teen drama level cheesy.

But he read it again.. And then again.

And again.

By the fourth time, he was leaning on the locker, letter clutched between his fingers like it was some sacred artifact. He skimmed the lines, lips curled in amusement, but his eyes softened with every reread.

And then, just as he was about to fold it back..

He saw it.

Tiny, scribbled, almost like an afterthought, tucked in the bottom right corner.

"Nani."

Sky froze.

The beat in his chest thumped once, hard.

".. No way.." He breathed out, eyes wide, the corners of his lips twitching up in slow disbelief.

Sky’s entire face lit up with mischief and surprise, like he’d just stumbled on the juiciest secret of the century.

He stood up straight, still staring at the name like it had unlocked something delicious.

"Looks like I just become the main character of a romance novel." He whispered with a grin, tapping the letter to his chest.

And that was the beginning of the end.. for Nani’s peace, and for Sky’s new favorite hobby.

By noon, the letter had unofficially become a class relic.

Sky didn’t let the moment die.

Not once.

He brought the letter out three separate times during class, each time for a new dramatic reading session. During a boring lecture, during lunch, and even mid-presentation when he was asked to share his group’s findings.

"Sorry, I got distracted.." Sky said, holding up the folded pink note like it was a scroll of wisdom.

"My fan-mail keeps calling to me."

Nani sat at the far end of the room, head low and his soul halfway to hell. He had mastered the art of going invisible while physically being present, but Sky’s teasing was like a flashlight in the dark.

"Oh, this one’s my favorite line.." Sky said loudly, casually quoting..

"You are the sunshine to my rainy days."

Giggles erupted. Eyes flicked around, whispering, speculating.

Nani wanted the earth to swallow him whole.

Worse, Sky never said his name. Not once. But every time he read the letter, he would glance.. just briefly, toward Nani. Just enough to make sure he knew. Just enough to remind him.. I have your heart in my back pocket.

Nani didn’t respond. Not with words, at least.

Just with death glares and the occasional cold sip of coffee, which only made Sky’s grin widen like he was fueling himself off Nani’s suffering.

By the time class ended, Nani was mentally packing his bags.

Maybe he could transfer to another faculty.

Or another university.

Or another country.

Yes. Yes, Bangkok was now too small for him. He needed to move. Maybe to Japan. Or Nepal. Somewhere with mountains and no signal. Somewhere Sky Wongravee didn’t exist.

He angrily left the university with a storm cloud over his head.

It was the quiet of the night. Nani was done with everything.. ready to sleep and wake up to a normal day.. hopefully.

His phone buzzed.

He ignored it.

Buzz.

With a dramatic sigh, he peeked at the screen.

[1 message from Sky]

"I didn’t know you had a crush on me. I’m flattered 💕"

"Are you ignoring me now.."

Nani stared at the text like it was cursed.

His ears burned.

His dignity was already buried, but this? This was poking the corpse.

He pressed call without thinking.. Sky picked up after two rings, voice soft, amused.

"Can’t sleep without hearing my voice?"

Nani groaned. "The letter’s not for you."

"Sure, sure." Sky chuckled.

"You accidentally wrote me a full K-drama confession letter. It happens."

"I didn’t write it for you." Nani snapped, sitting up, exasperated.

"It was meant for someone else. I.. I slipped it in the wrong locker, okay?"

There was silence on the other end.

The quiet lasted for some seconds..

Then—

"Wow."

Nani blinked. "What?"

"What a creative excuse." Sky’s voice practically smirked through the phone.

"You got caught being soft, and now you’re panicking. Adorable."

"I’m not panicking."

"You’re panicking.. very much."

Nani gritted his teeth. "Even if you were the last person on earth, I would never have a crush on you."

"Ouch.." Sky said cheerfully.

"Now my feelings are hurt. Are you rejecting your fake love confession?"

"I am rejecting your entire existence."

Sky laughed. 

"I’m hanging up.." Nani muttered, already pulling the phone away from his ear.

"Sweet dreams, sweetheart." Sky teased.

"Don’t forget to dream of—"

Click.. Call ended.

Nani stared at his phone, face on fire. His entire night was ruined. Tomorrow, he was going to march up to Sky and clear the misunderstanding once and for all.

.. or maybe punch him.

Either worked.

Meanwhile, across the city, Sky sat cross-legged on his bed, phone still in hand.

The letter rested beside him.. slightly creased from being unfolded and refolded too many times. He’d read it over a hundred times now.

Even if it wasn’t meant for him as he found out already.. Sky still held it like it was something precious.

He pressed a finger over the small name scribbled at the bottom.

"Nani."

His smile softened.

He didn’t know why it mattered.

It just did.

"Your smile makes the worst days better.."

He scoffed out loud, rolling his eyes at himself.

"Get a grip, Sky."

Nani had always been too cool. Too collected. Always unbothered in class, giving Sky those bored, blank stares.

So seeing him squirm, embarrassed and shy..it was fun.

He tossed the note onto his nightstand, sitting up with a satisfied grin.

And okay.. maybe part of him was curious for whom it actually is for.

Because, come on.

Nani having a crush on someone.. and then writing a cheesy letter?

It wasn’t the usual "you’re hot, date me" note. It had warmth. Thought. A kind of softness.

Somewhere in the chaos, it had become.. personal.

Not because he think it was for him. But because Nani wrote it. Nani, who rarely spoke unless forced to. Nani, who always looked tired but still showed up. Nani, who secretly ate strawberry Pocky behind his textbook when he thought no one was watching.

And Sky had caught him more times than he could count.

He didn’t know what it meant.

Yet..

But he knew one thing.

He wasn’t letting this go anytime soon.

The Next day Sky entered the class twenty minutes late with a smoothie in one hand and the love letter poking out of his notebook like a flag of war.

He spotted Nani immediately..hood up, headphones in, face like death warmed over.

Sky slid into the seat beside him, uninvited, as usual.

"Morning, secret admirer." He whispered with a smirk.

Nani didn’t look at him.

Sky leaned closer. "Slept well? Dream of me?"

"I dreamt of pushing you off a cliff." Nani said flatly, still not looking at him.

Sky grinned. "So now we are in 'dying for each other' arc."

He love this.. teasing Nani and all.

But somewhere deep inside, under all the laughter.. 

He was starting to wonder what it would feel like if Nani ever wrote him a real letter like that.

One meant for him.

It was lunch break and Nani had enough of Sky's teasing.

The moment he spotted Sky sauntering down the hallway, juice can in hand, smug aura in full effect.. he grabbed his wrist and yanked him into the quieter corridor near the stairwell. It was the one spot in the business building barely anyone passed through during break.

Sky blinked, amused. "Oh? Rough already? And here I thought you wanted romance first."

Nani slammed his hand against the wall beside Sky’s head, face dark, ears red.

"Give it back.. It’s not for you." He said, voice low and flat.

Sky raised a brow, unbothered as always. "The letter?"

"No, the juice. Of course the letter." Nani snapped, then pinched the bridge of his nose.

"Look, I didn’t mean to put it in your locker. I made a mistake. So just.. give it back."

Sky tilted his head with a slow, teasing grin. "Hmm. Can’t do that."

Nani’s eyes narrowed. "Why not?"

"Because.." Sky said, pressing a dramatic hand to his chest.

"It’s my first ever love letter. I’m going to cherish it with my life."

"You’re unbelievable."

"Well, technically it was in my locker. Which means it’s mine now. That’s how possession works, right?" Sky added, voice silky.

"It’s not even for you." Nani said, exasperated.

"Why are you keeping it like it’s a national treasure?"

"Because someone poured their heart into that letter. And I may be many things, Nani.. but I’m not heartless."

"You’re a headache. A walking, chaotic headache." Nani groaned and leaned against the wall, visibly crumbling.

"One time. One time I try to be brave, and you happened. I must’ve been cursed in a past life."

Sky grinned wider, clearly enjoying every second. "You call it a curse. I call it good luck."

"That letter was cheesy as hell btw. Like, where did you even get all those lines? Pinterest? A rom-com?"

Nani covered his face with both hands.

Sky chuckled, then softened, just a touch. "But.. I liked it. Really. Even if it was over-the-top, it was.. kinda nice."

He leaned closer, mischief twinkling in his eyes.

"Accept the fate. I got the letter. From you. So it’s mine now."

And right then.. of course, fate or Nani's bad luck struck again.

Two girls from their class turned the corner, clearly mid-gossip, only to freeze when they heard the words and saw them standing suspiciously close by the stairwell.

All four of them locked eyes.

No one moved.

Sky had one hand on his hip and the smirk of a man who knew he was living in someone else's fanfiction. Nani looked like he was trying to melt through the floor tiles.

Then..

"OH MY GOD!" One girl whispered. 

"Nani was the one who gave Sky the love letter." The other one gasped, already grabbing her phone.

And just like that, they took off running, straight back to class, no doubt.. to spread the news like wildfire.

Sky clicked his tongue. "Well. I guess now the entire university’s going to know."

Nani stared into the distance like he was watching his life collapse in slow motion.

"Kill me now."

Sky leaned in one last time, voice low and wicked. "If you want to write me a sequel, make it even cheesier."

Nani didn’t answer.

He was too busy planning a murder.

The moment Sky pushed open the classroom door, the room exploded.

"CONGRATULATIONS, SKY!!"

"OH MY GODDDD!"

"You bagged Nani!"

Confetti someone had definitely stolen from the events club showered from the ceiling like this was graduation and Sky had just proposed.

Sky blinked once. Then, like the natural performer he was.. he bowed.

"Thank you, thank you." He said, holding up an imaginary trophy.

"It was a long journey. Many obstacles. But in the end.. love conquered all."

Someone threw some leaves at him. Sky caught them and sniffed them dramatically.

He basked in the moment like he’d trained for it.

"He’s acting like he won the Bachelor Thailand." Someone shouted.

"Honestly, kinda slay though." Her friend whispered back.

Five minutes later, the door creaked open again.

Everyone turned in perfect unison.

And there stood Nani.

Wearing his usual bored eyes, headphones in, coffee in hand.. and an expression that screamed 'I regret being born.'

The room fell into a suspicious hush.

Mark whispered. "They’re entering separately now. Must be trying to avoid suspicion."

"Classic low-key lover behavior." Someone added.

Nani walked slowly to his seat like a man heading to his own execution.

He sat down, lowered his hoodie, and tried to pretend the cheering, giggling, and whispering around him didn’t exist.

"The love letter was like..poetry."

"It said something about the smile."

"#Skynani is trending in our faculty group chat, I'm screaming."

"My friend from the law department already reposted a meme about it."

"Wait, show me—YES THIS ONE! The one with Nani's death glare captioned. 'When bae won't stop teasing you.'"

Sky strolled over to his seat beside Nani and dropped into it like he was sliding onto a talk show couch.

He leaned in. "Hey, neighbor. I mean.. desk mate. I mean.. secret boyfriend."

Nani didn’t look at him but muttered. "I hope your smoothie spills on your white pants and you stub your toe."

Sky grinned. "Aww.. Is this how you flirt, love?"

"Die."

"You know.." Sky said, poking his notebook with a pen.

"You keep insisting that letter wasn’t for me.. but you’re doing a terrible job at pretending that I don’t affect you."

Nani stared ahead, face blank. "Yes you do! You are ruining my day.. my life to be exact."

"Thank you.. I guess. I’d like to thank fate, misplaced lockers, and your amazing taste in men." Sky said brightly.

More stifled giggles from the class because of them whispering. One student was live-tweeting the whole thing like a fan account.

Nani sank lower in his chair.

His phone buzzed. A message from an unknown number.

[Unknown]: "So... when’s the wedding?"

He groaned out loud.

Sky peeked over. "Ooooh, who’s asking? Should I send out the invites?"

Nani turned to him, deadpan. "I’m moving to another country."

Sky smiled and whispered. "I'll visit you. Long-distance love story. #Skynanilongdistance."

The entire class: "AWWWWWWWWWWW!"

Nani banged his head on the desk.
