EXT. BUSAN BEACH – MORNING TO NIGHT

The sun is high, the waves playful, and chaos is the language of love.

The squad is full vacation mode — water fights, volleyball, burned marshmallows, sandcastles gone rogue.

Rosé and Jisoo are locked in a ridiculous volleyball battle. Seulgi is building a "defensive sand bunker" with Mingyu and Jungkook, who are clearly just showing off muscles. Irene is applying sunscreen on Seulgi's neck like it's war paint.

Meanwhile, Lisa and Jennie walk barefoot near the tide, looking way too coupley for people supposedly "not telling anyone." Lisa's hair is wind-blown, cheeks flushed. Jennie? Sunglasses on. But her smirk screams mine.

NIGHT – BEACH BBQ

The grill sizzles. Laughter fills the air. Someone's awful playlist is booming.

JISOO
You call that a medium-rare? It's charred like my dating life!

MINGYU
You literally told a guy his star sign was a red flag.

ROSÉ
It was! He said "Scorpio moon" and blinked like he was dangerous.

JUNGKOOK
You've dated worse.

ROSÉ (mock offended)
Excuse me?

Everyone is howling.

Jennie passes Lisa a skewer and their hands brush—just a bit too tenderly. No one catches it—except Rosé and Irene, who are always watching.

They exchange a long, slow glance.

ROSÉ (loudly, to Irene)
So you still believe in casual relationships?

IRENE (grinning)
Oh yeah. Totally. Zero attachments. You?

ROSÉ
Completely unattached. Like Lisa and Jennie.

IRENE
Yup. Just two single girls. No romantic beach walks. No neck kissing.

Lisa chokes on her soda. Jennie hides behind her cup.

LISA
You're both deranged.

They all go quiet for a beat when Seulgi suddenly freezes mid-bite. Her eyes on Lisa's collarbone.

SEULGI
Hold up...

JISOO
Wait.

She leans in, eyes narrowing.

JISOO
Is that... is that a... ruby orb necklace?!

Gasps.

JUNGKOOK
Those are rare as hell. You can't just buy those last minute.

MINGYU
Is that your girlfriend's family heirloom, or are you just casually dating royalty?

ROSÉ
You don't shop for that. That's a declaration. That's a proposal in accessory form.

Everyone turns to Lisa. Lisa, mouth full of shrimp, pauses. Swallows. Licks her lips. Looks at Jennie, who's just smirking behind her beer bottle.

LISA (cocky, loud)
What?

The squad explodes.

JISOO
WHAT?!

SEULGI
ARE YOU SERIOUS—

IRENE
Is this real? Are you both actually soft now?

JUNGKOOK
I need to sit.

ROSÉ
Is the world ending?! Lisa the Untouchable got orb'd?!
