Jeon Jungkook started a fight again. In the school corridor you can hear the sounds of blows, swearing and loud exclamations from students around. A group of Jungkook's friends loudly shout at him and cackle. And Jungkook just growls in anger and hits his opponent hard in the jaw. The guy flies into the lockers and rolls to the floor with a dull groan of pain.
