Back at that summer
The moment that shot was fired, as a reflex he clutched his hand right in front of his face. He waited for the bullet to hit him, or in case the impact was way too quick to comprehend, the pain to hit him. When neither of those two happened for quite a long time he opened his eyes and removed his face from in front of his face.
He looked around to see everything stand still for a moment. Nothing moved, like when you put a pause in a video. For a moment he actually believed time stopped before he considered that maybe they just became still, until he saw the bullet yet in its path floating above the ground level in a perfectly still manner. What kind of bullet just stops in the middle and floats after it's left its nozzle.
After a few moments of failing to comprehend the situations he looked around. The moment he turned back he saw a familiar face staring at him.
