  "prompt": "A spontaneous smartphone-style eye-level medium shot of [Yunjin from LE SSERAFIM] working out inside a commercial gym. She stands on her left leg with her right leg extended laterally at a 30-degree angle, attached to a cable machine via a black ankle strap, left hand steadying herself on the machine frame, right hand on her hip, looking forward with an expression of focused effort. She wears a [charcoal gray two-piece workout outfit with a square-neck sports bra and high-waisted shorts], white sneakers, black over-ear headphones, layered gold necklaces, small hoop earrings, and a black smartwatch on her left wrist. Beside her on the right, [Kazuha from LE SSERAFIM] performs [dumbbell shoulder presses] with poised athletic posture and an intense, focused expression, wearing a matching [charcoal gray crop top and shorts], black sneakers, and hair tied in a high ponytail. The gym setting features dark rubber flooring, gray walls, weight racks, and background gym-goers softly reflected in large wall mirrors under bright, even overhead artificial lighting with soft natural shadows. Color palette dominated by charcoal gray, black, silver, and white."
