HOUSE OF CARDS - [STUDY GROUP]

At Yusung Technical High, strength isn't just about fists, it's about bloodlines. Seo Minjun, heir to the feared Dongcheon Group, walks the halls with power etched into his name. But power is a double-edged crown.

The Dongcheon and Yeonbaek empires, built by fathers, fueled by rivalry, tear at each other from the shadows. Phi Hanwool carries Yeonbaek's banner. Minjun, unwillingly, bears Dongcheon's. But the battlefield is more than just school corridors, it cuts through Minjun's own family.

Betrayal came twice. Once from his older brother. And once from Lee Hyunwoo, the boy who was more than a friend, the secret Minjun guarded in the dark. Hyunwoo, who abandoned him, who bled for Hanwool's side, who carried guilt like chains while Minjun's heart fractured. And when Hyunwoo's hands stained with blood at Hanwool's command, the world Minjun knew collapsed.

Two heirs. Two dynasties. Two brothers divided. Between revenge and loyalty, love and betrayal, blood and ruin... only one throne will remain standing.

And one of them must fall.
