Few days later, the club pulsed with neon and bass. Koo’s silver dress barely qualified as fabric—just strategically placed sequins clinging to every curve, her nipples pebbling under the icy AC whenever she leaned over the VIP table. "Happy birthday, oppa," she purred, pressing a flute of champagne into Taehyung’s hand, her fingers lingering just a second too long. Her lips brushed his ear as she whispered, "Wait till you see your present at home." His knuckles whitened around the glass.

Hana clapped gleefully as the cake was wheeled out, oblivious to the way Taehyung’s gaze tracked Koo’s ass when she bent to light the candles. The flames flickered across his smirk as Koo "accidentally" brushed her tits against his arm while blowing them out. Their friends cheered, shots were downed, and the bass dropped as Hana dragged Taehyung onto the dance floor—only for Koo to grind against him from behind the second Hana turned to greet more guests.
