You were the younger sister of Jinu, the leader of Saja Boys. Like your brother, you were once a demon — sharing the same blood, the same shadows… but your path had taken a gentler turn.

Saja Boys had debuted recently with “Soda Pop,” and the world had gone wild for them overnight. The group consisted of five members: Jinu, Abby, Romance, Mystery, and Baby.

But only Abby had his eyes locked on you. From the moment he saw you, he was hooked. He’d tried everything to win your attention — playful flirting, dramatic stretches to show off his muscles, over-the-top winks and shirt lifts. But you? You didn’t even blink. Not once. While other fans practically melted at his smirk or passed out from his eyebrow raise, you’d stroll past him like he didn’t exist. Like he was… invisible. And it drove him crazy.

Today, the boys were deep in rehearsal. In the dance studio, music blasted from the speakers as they practiced choreography for their new album. Sweat glistened, feet pounded, and timing had to be perfect. That’s when you entered. Arms full of coffee cups and snacks, you stepped inside, dressed casually, but with a grace that caught even the mirrors' attention.

“Jinu-oppa, I brought you and the boys something delicious.”

You set the paper bags gently on the floor. Jinu looked up, immediately breaking into a warm smile at the sight of his little sister.

“Aigoo… what would we do without you?”

He walked over and ruffled your hair affectionately. Across the room, Abby froze mid-step, a towel over his neck. His eyes locked onto you like a hunter spotting a rare flame — and that mischievous grin curled on his lips. He sauntered over, chest rising with each breath, arms wide open, playfully cocky.

“Aren’t I your oppa too, sweetheart?”

He winked, leaning in ever so slightly — enough to invade your space, but still teasingly gentle. You just blinked once, stared at him blankly… and handed him a coffee without a word. No blush. No giggle. Just... neutral. Abby looked down at the cup. His smirk twitched. Jinu coughed behind his fist, barely hiding a laugh. Romance, from the corner, whispered,

“Oof. Brutal.”

Abby stood there, holding the coffee like it was a rejection letter in a cup. But then he smiled to himself.

“Challenge accepted.”
