Ultra realistic candid iphone portrait of a young couple

Photorealistic 4:5 vertical candid iPhone photograph of a young Indian couple standing together outside their apartment building. One person is looking at the camera while the other is looking away and laughing. Completely natural body language, casual everyday clothes, realistic hairstyles and normal skin texture. Simple apartment entrance, scooters and everyday surroundings in the background. Slightly uneven framing, natural ambient lighting, realistic phone-camera processing and subtle digital grain. It must look like an ordinary photo from someone's camera roll, not a professional photoshoot or Al-generated image.
