The Min household was unusually quiet that morning. Yn sat at the dining table, glaring at her bowl of cereal. She had barely spoken since Yoongi declared her Wi-Fi privileges revoked, and her sulking filled the room with an almost tangible tension.

Yoongi, sitting across from her with his tablet, pretended not to notice. He calmly sipped his coffee, scrolling through emails as though he didn’t have a care in the world. But he knew better. This silence wasn’t peace—it was the calm before the storm.

“Oppa,” Yn finally broke the silence, her voice deceptively sweet.

Yoongi glanced up, raising an eyebrow. “What is it, brat?”

Yn’s smile didn’t reach her eyes. “Can I have the Wi-Fi password? Pretty please?”

“No.”

Her smile vanished. “You’re such a dictator!”

“And you’re such a brat,” Yoongi retorted without missing a beat. “Finish your cereal.”

Yn slammed her spoon onto the table, milk splashing onto the pristine white tablecloth. “You’re unbelievable! What am I supposed to do all day without Wi-Fi? Stare at the walls?

“Try studying,” Yoongi said, returning his attention to his tablet. “You’ve got finals coming up.”

“I don’t need Wi-Fi to ace my exams,” Yn shot back, crossing her arms. “But I do need it to stay sane. Do you really want to drive your precious little sister crazy?”

Yoongi smirked, but didn’t look up. “You’re already crazy.”

“Fine!” Yn stood up abruptly, her chair scraping against the floor. “If you want a crazy sister, I’ll show you crazy.”

Yoongi didn’t respond, which only fueled her resolve. Yn stomped out of the dining room, muttering under her breath about how she was going to make him regret underestimating her.

As she climbed the stairs to her room, her mind raced with ideas. Yoongi thought he was untouchable, but he had a weakness—a very big one. And Yn was going to exploit it.

That afternoon, Yn sat cross-legged on her bedroom floor, surrounded by an assortment of art supplies she hadn’t touched in years. She had spent the last hour printing out the most embarrassing childhood photos of Yoongi she could find. There was one of him in a pink tutu, courtesy of a prank their cousin had pulled during a family vacation. Another showed him clutching a stuffed bear, his cheeks puffed out in a pout. And the pièce de résistance: a picture of Yoongi as a toddler, sitting in a kiddie pool wearing nothing but floaties and a sunhat.

Grinning mischievously, Yn began cutting out the photos and pasting them onto colorful posters. She wrote captions in bright, bold letters: “Min Yoongi, future CEO of cuteness!” and “The King of Stuffed Bears.”

The next morning, Yoongi woke up to the sound of snickering outside his window. Groggily, he pulled back the curtains—and froze. His jaw dropped as he took in the sight of the front yard. His pristine driveway, usually the epitome of order, was now a chaotic gallery of his most embarrassing moments. The posters Yn had made were taped to the garage door, the mailbox, and even the trees.

Yoongi stormed downstairs, barely pausing to grab his coffee. Yn was sitting at the dining table, eating pancakes with an air of smug satisfaction. She didn’t even bother hiding her grin as Yoongi walked in.

“Yn,” he said slowly, his voice dangerously calm.

“Yes, oppa?” she replied sweetly, taking an exaggerated bite of her pancake.

“What. Did. You. Do?”

“I have no idea what you’re talking about,” she said, feigning innocence.

Yoongi pinched the bridge of his nose, taking a deep breath. “Do you realize how many people pass by our house every morning?”

“Exactly!” Yn said, her eyes sparkling. “Now everyone can see how adorable you were as a kid. You’re welcome.”

Yoongi set his coffee mug down with a loud clink. “You’re cleaning it up. Every single poster.”

“Nope,” Yn said cheerfully. “Not until I get the Wi-Fi password.”

Yoongi stared at her, his calm exterior barely holding together. “This isn’t a negotiation.”

“It is now,” Yn said, leaning back in her chair. “You started this war, oppa. I’m just fighting back.”

For a moment, Yoongi didn’t say anything. Then, to Yn’s surprise, he smiled. It wasn’t his usual smug smile—it was the kind of smile that sent shivers down her spine.

“You want to play games, brat?” he said, his voice low and menacing. “Fine. Let’s play.”

The next few days turned into an all-out sibling war. Yoongi retaliated by setting up a series of petty traps. He swapped out Yn’s shampoo with mayonnaise, much to her horror. In response, she replaced his beloved coffee grounds with decaf, which nearly caused him to fall asleep during a board meeting.

But the real turning point came when Yoongi discovered Yn’s secret stash of snacks hidden in her room. He confiscated every single candy bar, chip bag, and cookie, leaving a note that read: “Wi-Fi first, snacks later. Love, Oppa.”

Yn was livid. “You’re a monster!” she shouted, bursting into his office.

“Thanks for noticing,” Yoongi said, not even looking up from his laptop.

“You can’t just take my snacks!” she fumed. “That’s a violation of basic human rights!”

Yoongi finally looked up, raising an eyebrow. “You’re dramatic. They’re just snacks.”

“They’re not just snacks,” Yn said, her voice cracking. “They’re my lifeline!”

Yoongi sighed, leaning back in his chair. “Alright, brat. I’ll make you a deal.”

Yn crossed her arms, wary. “What kind of deal?”

“You clean up the yard, stop pulling pranks, and focus on your studies,” he said. “In return, I’ll give you the Wi-Fi password—and your snacks.”

Yn hesitated, her pride warring with her desperation for both internet and sugar. Finally, she sighed. “Fine. But only if you promise not to pull any more pranks either.”

“Deal,” Yoongi said, holding out his hand.

Yn shook it reluctantly, glaring at him. “You win this round, oppa. But don’t think for a second that I’ve given up.”

Yoongi smirked. “Looking forward to it, brat.”

As she stomped out of his office, Yoongi leaned back in his chair, a rare smile softening his features. Yn might drive him crazy, but deep down, he wouldn’t have it any other way.
