ชายหนุ่มอนิเมะในค่ำคืนฤดูหนาวท่ามกลางหิมะ

Anime-style illustration of a gentle young man in his early twenties with short black hair, standing on a city street at night in winter. He is wearing a dark blue coat and a gray scarf, looking down at [a small letter] with a soft expression. Snow falls quietly around him against the blurred bokeh lights of a festive city. Delicate line art, gentle atmosphere, and warm Christmas ambiance.
