Create a romantic black-and-white studio portrait of a real skinny

Create a romantic black-and-white studio portrait of a real skinny, not medium weighed, couple standing in front of a wall with a heart-shaped light projected behind them. The couple must maintain their real and original faces, preserving all authentic facial features and natural hair colors, with no changes. The man is leaning toward the woman, gently smelling her neck with a soft and loving expression, while holding her hand. The woman smiles slightly, with a romantic and affectionate look. Their outfits remain the same: the man wears a plain fitted white t-shirt and light pants, while the woman wears a sleeveless white top and dark jeans. The lighting is dramatic with strong contrast, highlighting the couple within the glowing heart shape. The image should be ultra-high resolution, with hyper-realistic details and a professional editorial photography style. 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.
