The couple stands close, facing each other with affectionate eye contact and soft smiles. Man: black tailored suit jacket with a white turtleneck underneath, clean classic styling. Woman: elegant fitted red satin dress with thin straps, thigh-high slit, red long gloves, sleek high ponytail, glamorous evening makeup, pearl/diamond necklace. Pose: man’s hands gently around her waist/hip area (respectful, natural), woman leaning toward him with a joyful expression. Background: cozy modern interior with a decorated Christmas tree on the right side (warm lights, gold ornaments), soft bokeh. Lighting: warm indoor ambient + subtle on-camera flash vibe, gentle shadows, cinematic warmth. No text, no logos, no watermark."
