Romantic Couple Portrait

Photorealistic 4:5 vertical iPhone photo of a young Indian couple casually walking together on a normal Mumbai residential street in the evening. They are talking to each other and smiling naturally, not posing for the camera. Everyday casual clothes, slightly messy hair, natural skin texture, realistic facial proportions, ordinary buildings and parked scooters in the background. Natural street lighting, realistic shadows, slight phone-camera noise, imperfect framing and exposure. Shot on an iPhone rear camera. No cinematic lighting, no dramatic color grading, no artificial bokeh, no beauty filter, no perfect skin. It should look exactly like a random photo taken by their friend.
