The merge

A man's hand is cut by a knife, causing blood to drip onto his palm. The scene shifts to a nighttime park where a man and a woman stand facing each other, holding hands. The woman runs away from the man, who remains standing. The man then looks at his wristwatch as steam or smoke rises from his arm. A close-up shows a man with long hair and a suit looking up in shock. The man in the light-colored shirt is then seen falling backward onto the ground. The setting is a dark, outdoor park at night, illuminated by streetlights and featuring a central circular platform with flagpoles.
