Bless this man

A man with glasses and a blood-splattered shirt holds a mug that reads "DON'T MUG ME" in a room with a bookshelf and a wall with red splatters; he then appears in a different outfit, standing with one hand raised against a wall, followed by a scene where he is in a dark, industrial setting with a large machine, and finally, a close-up of his face in a dimly lit, green-tinted environment.
