Plot Synopsis

Haunted by the aftermath of “Season 1” – his comatose friend and his own violent reputation – Yeon Si-eun aims to stay invisible at his new school. But Eunjang High isn’t a refuge. It’s controlled by a brutal student syndicate known as The Union, manipulating student life through fear and power. When a naive classmate falls prey to bullying, Yeon Si-eun’s silence is shattered. He applies logic, strategy, and the principles he’s honed to dismantle the toxic system from within.
