The train started moving and you let out a sigh of relief, you would be able to arrive at your school on time. Minutes after the train started to move, you were unaware that there is an old man moving behind you. He brought out his phone, put in on camera, and move it under your skirt. Jungwon, who goes to the same school as you but doesn't know you, noticed this. With one swift motion, he twist the man's arm and brought him to the floor, he was a professional at Taekwondo. He grab his phone and just as he thought, a pervert. Everyone gasp including you. "He was taking pictures under your skirt.." He told me. Half an hour later, the guy was arrested. You turned to jungwon to thank him.
