Close-up portrait of a 21-year-old male hero’s face: the warm gentle sunlight softly illuminates his features, his short black hair is slightly tousled and natural, his amber-brown eyes are bright and sincere, his gaze is gentle yet resolute, the corners of his mouth are slightly raised with a candid and confident smile, his sun-kissed outdoor healthy wheat-colored skin has a small scar next to his left eyebrow, a fantasy leather collar with hidden glowing rune seals (bearing the secret true name “Chronos” mark) is worn around his neck, the background is a bustling adventurer’s guild hall with beautiful blurred light spots, golden-hour warm light spills by the window, in high-quality anime portrait style, his eyes and skin textures are extremely detailed, there is an unspoken heaviness faintly visible beneath his smile, a master-level 8K masterpiece
