You crossed your arms, standing by the door as your brother slipped on his jacket.

“I’ll be back tomorrow afternoon,” he said. “Don’t set the house on fire.”

“I’m not twelve,” you snapped.

He ignored the attitude, instead patting Sunghoon’s shoulder as he passed. “Take care of her, yeah?”

You rolled your eyes so hard it almost hurt. “I don’t need a babysitter.”

Sunghoon gave a lazy smirk from the couch, legs stretched out, arms resting behind his head like he owned the place. “Trust me, I’m not thrilled about it either.”

You scoffed and turned away, muttering something under your breath.

The night passed slowly—annoyingly. You kept to your room, headphones in, pretending he wasn’t there. But around midnight, the silence got boring, and you drifted to the living room in search of snacks.

Sunghoon was still awake, lying on the couch, scrolling through his phone.

“You always this grumpy when your brother’s not around?” he asked without looking up.

You glared. “You always this annoying when you’re not sucking up to him?”

That made him laugh—quiet and low. “Cute.”

You blinked. “Excuse me?”

He finally looked up, eyes locking with yours. “It’s kind of funny. You act like you hate me, but you’re always watching.”

You opened your mouth to argue—but came up empty.

He stood slowly, stepping closer, a hint of something unreadable in his gaze. “Maybe you just don’t know what to do with me when your brother’s not around.”
