Just because

A young woman with short dark hair and purple eyes looks forward with a neutral expression, holding a knife in her right hand, in a room with a yellow wall and a framed picture. A young man with black hair and purple eyes, wearing a white hoodie, stands with his arms raised against a blue sky, then appears in a close-up with a strained expression, his face held by two hands, his mouth open as if shouting. Two men with intense, grinning expressions face each other in a dark setting. The sequence ends with a black screen.
