Story
At an elite private high school, students from wealthy families set the rules of the game; the upper echelons hold the top positions of power on campus, while An Ran, who just wants to keep a low profile, is reduced to being a scapegoat. When he is bullied by his classmates yet again, he is unexpectedly rescued by his twin brother, whom he had been separated from since childhood.
