Eunjang High was never a peaceful place. Fights broke out in every corner, and bullying crushed the weakest kids.
It was the only school in the neighborhood not under the control of the Union - a delinquent gang that had grown into something like a mafia ruling the city.
Its leader, Na Baek-jin, wanted Eunjang under his fist at any cost. Not because he cared about the school - but because his old childhood best friend, Park Hu-min, was the reigning top dog there.
So Baek-jin did what he always did. He sent his best fighter. Someone reckless, merciless, unpredictable.
Geum Seongje - the Union's most dangerous weapon.
But when Seongje set his sights on Park Hu-min and his crew, one face stood out.
Ryu Seorin
A new girl, unlucky enough to cross paths with Hu-min's gang.
What no one realized was that Seorin wasn't just another transfer student.
She was one of the most dangerous operatives trained by the Pyongyang regime - a weapon forged in the 11th Division, a covert unit of elite spies sent south. She had spent her whole life training for one purpose: survival. For her mission. For her little sister.
Seorin had no time for schoolyard wars, for the Union, or for the unfamiliar ache stirring in her chest.
But it didn't matter. Because both Geum Seongje... and Park Hu-min... had already set their eyes on her.
