Four guys

A young man with spiky black hair and a headband appears in a series of quick cuts, first shown in a bright, overexposed frame, then in black and white pointing forward, followed by a close-up of his face, a scene with him giving a thumbs-up in a classroom, and finally a side profile of him running. The sequence alternates between different lighting and color styles, showing the character in various emotional states and settings, including a classroom and a dark environment.
