Echo of terror

A young man with dark hair and a collared shirt appears in a series of contrasting scenes: he is shown with a neutral expression against a black-and-white background, then laughing with eyes closed against a blue, watery backdrop, followed by a smirking expression in a green-lit, dim environment, and finally with a distorted, glitching effect. The sequence cycles through these emotional states and visual styles, alternating between calm, joyful, and sinister moods.
