Duration: 7 secondsAspect ratio: 9:16 verticalStyle: Minimalist hand-drawn animation, charming, emotional, cinematic, clean white background.REFERENCE LOCK: Use the uploaded image as the exact starting frame. Preserve the stick figure's original design, black sketch outlines, facial features, red heart shape, white background and simple hand-drawn aesthetic. Do not turn it into a 3D character.0–2 seconds — A little spark of loveThe stick figure gently balances on one leg, making a tiny natural wobble. Its raised arm reaches toward the red heart. The figure blinks once, and its small smile grows slightly warmer. The heart gives a gentle, rhythmic pulse, growing just a little larger and returning to its original size. A subtle red glow appears around its edges.2–4 seconds — The heart comes aliveThe heart floats upward by a few centimeters, then gently bobs back down as if weightless. The stick figure follows it with its eyes and stretches its raised hand a little higher. Its free arm and lifted leg sway naturally to maintain balance. A few tiny red and pink hand-drawn sparkles appear around the heart, drifting slowly upward before fading.4–5.5 seconds — The magical connectionThe heart releases a delicate trail of glowing red particles that spiral softly around the figure's raised hand. The figure looks delighted, tilts its head slightly, and gives a joyful little bounce without leaving its original position. The heart pulses once more, brighter and warmer, casting a faint red glow on the nearby sketch lines.5.5–7 seconds — The perfect endingThe heart gently descends until it rests just above the figure's raised hand, as if the figure is offering love to the viewer. The stick figure settles into its original pose with a sweet, contented smile. The sparkles fade slowly, leaving the red heart glowing softly. End with the composition almost identical to the starting image, creating a seamless loop.CAMERA: Mostly static camera with a very subtle cinematic push-in throughout the clip. No rotation or shake.MOTION STYLE: Gentle, smooth, expressive, hand-drawn animation. Slight line wobble to preserve the sketch aesthetic. The heart's pulse should feel warm and rhythmic, not like a rapid heartbeat.LIGHTING: Keep the white background clean. Use only a subtle red glow around the heart and tiny glowing particles.NEGATIVE PROMPT: No 3D transformation, no realistic human anatomy, no extra limbs, no distorted stick figure, no changing facial design, no heart deformation, no background changes, no text, no camera shake, no excessive sparkles, no fast motion, no flickering outlines, no sudden zooms, no watermark.
