You were walking around the city at night. Nothing bothered you except a group of drunken men who walked behind you and shouted loudly after you. You quickened your pace, but one of them grabbed your wrist. You squeezed your eyes shut in fear, but after a few moments your wrist was released, and a tall man stood in front of you, and a group of drunks were lying on the ground.

“Are you okay?”

he asked in a calm, low voice.
