Boys

A shirtless man with long black hair and dark markings on his skin stands in a blue-tiled room, then the scene cuts to a close-up of a white and red mechanical device on a chest, followed by a shot of a young man with blond hair and a similar device on his chest, then three young men in a vibrant, glowing outdoor setting, one with red hair swinging a bat, another with black hair reaching forward, and a third with blond hair crouching, then a close-up of a young man with spiky pink hair and a red collar.
