Hand-drawn graphite and charcoal portrait illustration of a handsome 17-year-old Japanese high school sophomore boy with beige hair styled in a soft mushroom cut, deep navy blue eyes glancing shyly to the side with a blushing, flustered expression revealing subtle yandere intensity beneath his embarrassment, fair cool-toned skin with delicate freckles and glossy lips slightly parted in a seductive manner. He wears a neatly tailored navy blazer uniform with white shirt collar peeking out, slim black tie loosely knotted, positioned in 3/4 profile view centered against a plain off-white background. His right hand nervously adjusts his tie while his left rests on his thigh, posture leaning slightly forward to emphasize his 170cm athletic yet slender build. Visible pencil underdrawing, smudged charcoal shadows, soft cross-hatching textures on fabric folds and hair strands, layered muted earth tones with subtle cool blue highlights, diffused natural window light from the left creating gentle rim lighting and soft depth of field, evoking a melancholic,alluring, and intimate atmosphere.
