This oneshot gives Fuma his final moment of victory, K's absolute breakdown, and the group losing their minds all over again. 😂🔥 But let's be real—this war is never truly over. Let me know if you want one last showdown! 😉✨

*****
You're so cute when you're flustered.
*****

K had been relentless.

Throughout the entire concert, he had made Fuma's life difficult.

Little nudges when the lights were low, teasing whispers in between songs, purposefully standing just a little too close when Fuma needed space.

At one point, when Fuma was trying to focus on his solo, K had leaned in, lips barely moving, and muttered,

"Don't mess up."

Fuma had almost lost it.

And K knew exactly what he was doing.

So after the concert, as they walked back to the dressing room, K was still grinning.

And Fuma?

Fuma was plotting.

The dressing room was buzzing—staff moving in and out, members wiping sweat off their faces, changing out of their stage outfits.

K, still smug from his teasing spree, was lounging on the couch, drinking water like he hadn't just tormented Fuma for hours.

Fuma stretched his arms, rolling his shoulders.

Then, casually, he walked over and stood directly in front of K. "Had fun out there?"

K smirked, tilting his head. "You looked like you were struggling. Cute."

Fuma narrowed his eyes.

Oh, K wanted to play?

Fine.

Fuma could play too.

Instead of snapping back, Fuma smiled.

It was too sweet, too deliberate.

"Oh, K," he sighed dramatically, lowering his voice just enough. "You were amazing out there."

K blinked.

Fuma tilted his head, stepping just a little closer.

"Really captivating," Fuma continued. "I could barely take my eyes off you."

K's smirk faltered. Just for a second.

Fuma barely held back his grin.

But he wasn't done yet.

He reached out, brushing a stray strand of hair off K's forehead.

Just like K had done to him earlier on stage.

K froze.

Fuma leaned in slightly, lips quirking up.

Then he whispered, "You're so cute when you're flustered."

The room went silent.

Nicholas, across the room, slowly turned. "Wait. What just happened?"

Taki, witnessing everything, gasped so loudly it echoed. "Fuma—DID YOU JUST TEASE K?"

Jo choked on his water. "That's illegal."

Yuma was wheezing. "K froze. He actually froze."

Harua, who had been casually fixing his hair, glanced up. "Hm. Interesting."

Meanwhile, K finally snapped out of his shock.

His ears felt too warm. His chest felt too tight.

So he did the only thing he could think of.

He shoved Fuma away. "I hate you."

Fuma beamed. "No, you don't."

K scowled. "I really do."

Fuma shrugged. "Then why are you blushing?"

K's jaw clenched. "I AM NOT—"

Nicholas, enjoying this far too much, grinned. "K, I think you just got outplayed."

Taki snickered. "How does it feel?"

K glared at all of them. This was a disaster.

Fuma patted his shoulder. "Better luck next time, boss."

And just like that—

Fuma won.

Later that night, after the chaos had died down, K was still thinking about it.

Lying on his bed, staring at the ceiling, he hated how smug Fuma had looked.

And worse?

K couldn't even be mad.

Because...

It was kind of fun.

Having someone who could throw it back at him.

K smirked to himself.

Fine.

Fuma had won this round.

But K wasn't the type to let things go.

So, when Fuma had successfully flustered him after the concert, K knew one thing for sure—

He had to get him back.

And not just any revenge.

It had to be perfect.

So, K waited. Plotted.

And when the moment came, he struck.

A few days later, Fuma had completely let his guard down.

They were backstage at rehearsals, waiting for their turn to practice. The members were scattered—some chatting, some on their phones, and Fuma, oblivious, was casually leaning against the wall, sipping water.

That's when K saw his chance.

Time for payback.

He strolled over, stopping right in front of Fuma.

Fuma looked up, raising an eyebrow. "What?"

K smirked. "Nothing. Just admiring the view."

Fuma nearly choked on his water. "...What?"

K stepped closer, lowering his voice. "You know, Fuma... You looked really good today."

Fuma froze.

K tilted his head slightly, the exact same way Fuma had done to him days ago.

And then, in a soft, mockingly sweet voice, he whispered—

"You're so cute when you're flustered."

Fuma's soul left his body.

Fuma blinked rapidly. "Wait. What—"

K leaned in just a little more. "Something wrong?"

Fuma backed up against the wall. "You—You're copying me!"

K smiled. Slow. Smug. Dangerous. "Oh? You don't like it?"

Fuma was malfunctioning.

Taki, who had been eavesdropping from behind a speaker, gasped dramatically. "DID K JUST FLIRT?"

Jo, who had been drinking his smoothie, spit it out. "OH MY GOD."

Nicholas smirked. "This is the greatest moment of my life."

Yuma whispered, "Fuma is losing."

Harua, barely reacting, simply nodded. "It's over for him."

Fuma was indeed losing.

He pushed at K's chest weakly. "G-get away from me."

K chuckled. "Oh, now you're nervous?"

Fuma covered his face with his hands. "I HATE YOU."

K grinned, stepping back victoriously.

Revenge.

Successful.

For the rest of the day, Fuma refused to make eye contact with K.

Nicholas wouldn't stop laughing.

Jo was still recovering from the smoothie incident.

And Taki?

Taki kept reenacting the scene dramatically.

"Oh, Fuma," Taki sighed, batting his eyelashes. "You're so cute when you're flustered~"

Fuma threw a pillow at him.

K, watching from the corner, smirked to himself.

Game. Set. Match.

But Fuma?

Fuma clenched his jaw

Fuma refused to let K win.

K had gotten him good—too good.

He had flipped the script, teased him mercilessly, and completely wrecked his ability to function.

And now, every time Fuma so much as looked at him, K would smirk—that infuriatingly smug smirk—like he was untouchable.

Yeah. That wasn't gonna fly.

So Fuma did what any reasonable person would do.

He plotted his revenge.

And when the moment came, he struck.

A few days later, the opportunity presented itself.

They were in the practice room, going over choreography. The members were focused, sweaty and exhausted from running the routine over and over.

Which meant K was vulnerable.

And Fuma was patient.

So he waited—let K's guard drop, let him get comfortable.

And then, just as they finished a run-through, just as K was about to take a sip from his water bottle—

Fuma casually walked up behind him and whispered,

"Wow... K, you're really attractive when you're sweaty."

K spit out his water.

The entire room froze.

Nicholas, witnessing everything in real-time, gasped dramatically. "NO. WAY."

Taki immediately dropped to the floor, laughing. "HE—HE CHOKED—"

Jo, eyes wide, pointed. "DID YOU SEE HIS FACE?!"

Yuma was wheezing. "HIS EARS ARE RED."

Harua, as calm as ever, simply nodded. "That was unexpected."

Meanwhile, K was still coughing, trying to process what had just happened.

He turned to Fuma, eyes wide with disbelief.

"You—"

Fuma grinned innocently. "Yes?"

K glared. "You did not just say that."

Fuma tilted his head. "But it's true. You look really good when you're sweaty."

K malfunctioned.

Taki screamed.

Nicholas fell off his chair.

Jo hid his face in his hands. "I can't do this today."

Yuma, wiping tears from his eyes, sighed. "This is better than TV."

K was at a loss for words.

And Fuma?

Fuma was enjoying every second.

"Oh, K," Fuma sighed dramatically, reaching up to adjust K's damp hair, just like K had done to him before. "You're so cute when you're flustered."

K jerked away instantly. "NOPE."

Fuma cackled.

Nicholas cheered. "HE DID IT. FUMA ACTUALLY WON."

Taki collapsed from laughter. "HIS FACE—HIS FACE—"

K, visibly flustered, ran a hand through his hair. "I HATE YOU."

Fuma beamed. "No, you don't."

K groaned.

Fuma leaned closer, smirking. "You really do look good though."

K shoved him away. "SHUT UP."

And just like that—

Fuma won.

For real this time.

For the rest of the day, K refused to talk to anyone.

Nicholas wouldn't stop bringing it up.

Taki reenacted the entire scene multiple times.

Jo simply patted K's shoulder. "Tough loss, man."

Yuma, shaking his head, whispered. "Legendary."

And Fuma?

Fuma sat back, victorious.

Because K had started this war.

But Fuma had finished it.
