Create a warm natural photorealistic couple portrait

Create a warm, natural, photorealistic couple portrait inspired by the uploaded reference image. A young couple taking a close-up selfie together, with their faces naturally close to each other. Both have genuine happy smiles and a relaxed, affectionate expression. The woman has long dark-brown hair and natural makeup, wearing a casual dark top. The man has thick dark hair, light facial hair, a black casual T-shirt, and a silver chain with a small cross pendant. Preserve the same close-up framing, facial expressions, pose, hairstyles, clothing, and overall candid selfie feeling. Include the playful red heart painted between their cheeks. Background: simple modern indoor room with a large mirror and warm ceiling lights. Natural smartphone-camera look, realistic skin texture, authentic facial details, soft indoor lighting. Avoid excessive retouching or artificial beauty effects. Photorealistic, candid couple photography, high detail, natural colors, vertical portrait, 4:5 composition. Insert discreet watermark in the lower right corner of the image, vertical text (rotated 90°), written "aipromptlabs.online", Calibri Light font, white color with low opacity (semi-transparent), medium size. Extreme sharpness on the face, fabric texture and typography of the letters. Shot on Canon EOS R5, 50mm f/2.8, studio light.
