Unified style: 3D anime + dreamy particles + rose gold warm tones; Main elements: shimmering rose gold butterflies, silhouettes of the female and male protagonists, red thread, and heart-shaped halo; Texture: soft-focus highlights, volumetric lighting, light misty depth of field, delicate glow. Keyframe (final freeze-frame moment): Shot type: medium-close-up; Angle: eye-level; Camera movement: slow push-in + slight pull-down. The red thread forms a heart knot between the two, circling their waists, with the silhouettes of the embracing couple clear and gentle; Butterflies gently land on the heart knot, then transform into rose gold shimmering particles, drifting downwards (density gradually decreasing, brightness fading from 40% to 10%). A blessing appears in the bottom center of the screen: "May all lovers be united in marriage," in glowing rose gold text, with particles flowing along the strokes; enveloped in warm light, edges gradually darkening in preparation for a fade out.
