Candid Couple Smartphone Photo Dump Collage

Using the reference photo as the base for the man, create a realistic casual smartphone photo collage showing him with a girlfriend across [16 square snapshots arranged in a 4x4 grid with thin white borders]. Maintain his identity, hairstyle, age, [white sweatshirt], and candid non-model appearance consistently throughout. Include exactly one recurring female companion, [a young woman with long dark hair], styled naturally rather than like a glam model, wearing subtly varied outfits such as [a cream knit cardigan, a dark top, and a muted blue top]. The 16 snapshots feature authentic couple memories shot on a phone: a close mirror selfie together, a dark blurry selfie, an indoor peace-sign selfie, a night street selfie, a motion-blur close-up, an outdoor daytime shot under a tree, an indoor shoulder-leaning shot, a blurry affectionate shot, a seated restaurant shot with glasses on the table, a warm night bokeh shot, a rooftop or balcony mirror selfie with city lights, a nighttime urban walking shot, a cozy leaning-together shot, a shoulder-around pose, a close side-by-side portrait, and an intimate close crop. Imperfect smartphone framing, direct flash, slight motion blur, lens grain, and spontaneous candid composition resembling a genuine saved couple photo dump.
