Art style: Pixar-like 3D.
Close-up of the boyfriend in the white t-shirt on the cozy autumn street. First he sees the girl's happy face and smiles shyly and flattered, as if he thinks she is looking at him. Then he follows her gaze and spots the tall dark-haired man in the black shirt near the building. His smile fades, eyebrows knit together, eyes widen. By the end his face briefly turns comically red with jealousy. Warm golden light, vertical 9:16, 3D Pixar style.
