Candid Japanese Campus Friends

Create a photorealistic candid campus lifestyle photo of {argument name="main subject" default="a handsome Japanese male university student"} walking through a bright outdoor school corridor with his friend. The composition is vertical 3:4, medium close-up, eye-level, natural daylight, shallow depth of field, soft bokeh background. Show exactly 6 visible people: 2 foreground students and 4 blurred background students. The main subject is centered-left, slim, clean-shaven, with tousled black medium-length hair, soft youthful features, and a gentle smile while looking to the right at his friend. He wears a white raglan T-shirt with black sleeves and a faded gray graphic reading {argument name="shirt text" default="BROOKLYN NEW YORK CITY EST. 1634"}, blue jeans, and a black backpack over one shoulder, holding the strap with his left hand. The friend is partially cropped on the right in profile, wearing {argument name="friend outfit" default="a light gray hoodie and black backpack"}, speaking casually with one hand raised. The corridor has concrete columns, windows, sunlit floor shadows, and a bright academic atmosphere, with students walking in the distance. Style should resemble a realistic Japanese university promotional snapshot, natural skin texture, soft highlights, relaxed friendship, no dramatic posing, no watermark, no extra text beyond the shirt graphic.
