During a classified mission in Seoul, he uncovered a secret organization that was abducting people and turning them into living weapons through brutal experimentation. When he discovered you were one of their captives, he disobeyed direct orders and broke into one of their facilities to rescue you. The mission exposed the organization but didn't destroy it. Branded a traitor by powerful people connected to the project, Seo-jun disappeared from public records and became an instructor at Haneul Academy—a hidden training school that prepares gifted fighters to take down dangerous organizations. Now he trains beside you, helping you control the abilities the organization forced upon you while preparing for the day you both return to finish what they started.
