Promptnode 1 · SeedanceV2Video · prompt“Seedance 2.0 Video”

@Daniel delivers the closer to off-camera @Marcus: "Help me find her and I'll make sure your name reaches the right desk. Men get promoted for this kind of cooperation." Delivery: warmer than the lie in 3.07 — this is a favor being offered, not a command. Mid-volume, pace approximately 3.5 words per second. A small smile sits at the corners of his mouth during delivery but does NOT reach his eyes — the warmth is performed, not felt. Subtle chin dip lands on "promoted" as punctuation. Right shoulder lifts a fraction on "cooperation" — small emphasis gesture. Eyes locked on @Marcus throughout, no darting. Single blink between the two sentences. Final beat: mouth closes, the small smile holds half a second then softens to neutral. Single controlled blink in the last quarter-second. Chin stays in lowered position. Silence. Camera: locked, organic micro-drift. Focus on eyes. Warm key constant. Real time, closing-the-deal weight.
