Authentic tourist atmosphere but emotionally intimate.\n\nSubjects: ONE adult woman and ONE adult man. Facial identities must match the reference image EXACTLY. No facial stylization, no symmetry correction, no beauty enhancement.\n\nInteraction: the man gently kissing the woman on the cheek. Natural affection, candid moment, not posed.\n\nWoman: wearing a white spaghetti-strap summer dress, flowing lightweight fabric. Pearl stud earrings. Natural makeup, calm expression, soft smile.\n\nMan: wearing a crisp white button-up shirt, casually styled. Black crossbody camera bag. Relaxed posture, natural movement.\n\nCamera: handheld selfie perspective, slightly wide-angle, realistic arm extension visible. Authentic travel photography feel.\n\nLighting: natural daylight with soft shadows, realistic skin tones, no HDR look. Editorial realism, cinematic clarity. NO TEXT."
