No subtitles.\n\nShot 1 [0–5s]\nContinue from the first frame. Medium two-shot at eye level. Two children sit facing each other in a white bathtub. The girl lifts a small green bar of soap to her mouth like a microphone and whispers as if singing. The boy watches closely, curious and still. Warm tungsten light, cozy bedroom softly visible in the background. Subtle water ripples.\n\nShot 2 [5–10s]\nSlow push-in to a wider side angle revealing more of the room. The girl finishes, lowers the soap, then suddenly laughs. The boy relaxes and smiles back. The tension breaks into quiet laughter. Camera holds steady as the water gently moves. End on a calm, frozen childhood moment.",
