A male stoic philosopher with a well-proportioned and attractive physique

A male stoic philosopher with a well-proportioned and attractive physique, wearing classic tunics that drape slightly transparent over his body, subtly revealing parts of his shoulder. He stands in a dimly lit room, his expression a mix of shock and deep sorrow as he realizes the betrayal of a trusted friend. The friend's silhouette is visible in the background, holding a dagger behind his back, eyes cold and unfeeling. The lighting is dramatic, casting long, deep shadows across the stoic's face, emphasizing the texture of the marble-like skin and the subtle imperfections that suggest the weight of this painful realization. The background is dark and minimalist, focusing attention on the emotional tension between the two figures, with a strong vignette and a touch of grain for a timeless, tragic effect.
