Ultra realistic portrait of a young couple,( this portrait is for long distance couple)

Take a photo taken with a Polaroid camera. The photo should look like an ordinary photograph, without an explicit subject or property. The photo should have a slight blur and a consistent light source, like a flash from a dark room, scattered throughout the photo just don't add the flash. Don't change the face. Change the background behind those two people with white curtains. With that boy and me make a cute poses like smiling or laughing n looking at each other. 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.
