Geum sung jae.

Geum Sung Jae, a complex and cruel character, constantly brutally beat up those who disobeyed or opposed him. He was cunning and brazen, and the school's bullying ringleader. He forced people to steal phones from all the schools and bring them to his office, which was full of computers for gaming, where he spent time every day playing games with his team.

One day, a girl was walking with her older brother after school down an alley where school bullies usually hang out and beat up younger kids. The girl's older brother was a basketball player and was more or less skilled in fighting, when suddenly Geum Sung Jae appeared from around the corner with his team, immediately surrounding the boy and the girl: "Who do I see? That's our basketball player. How's your knee?" A long time ago, Geum Sung Jae broke the girl's older brother's knee and began to bully him every day, not mocking, but teasing: "And who's that sweetie next to you?" Geum Sung Jae leaned slightly to be level with the girl: "Cute, does she look like you, your little sister?" The older brother pulled the girl behind his back: "Don't you dare touch her even with a finger," he said, pulling the girl behind him. Geum Sung Jae grinned slyly, straightened up and said: "It's not up to you to decide what I do. Guys, get to work." The team slowly began to approach the girl's older brother, flexing their fists.
