Anime cinematic loop. A boy sits at a desk with sunlight coming through an open window. His left arm rests on the desk. His left index finger gently taps the wooden surface in rhythm:
1. Finger lifts slightly.
2. Finger goes down and touches the desk.
3. Subtle contact is visible, a soft impact.
4. Finger lifts again, repeating slowly.
The motion is calm, like a quiet metronome. Hair moves gently with the wind from the window. Highly detailed, smooth loop animation, realistic lighting, cinematic anime style.
