Episode 10 — titled 'The Last Fight' — opens with the study group discovering the full truth behind the tragedy that has haunted Yusung Technical High School for years. They learn that Han-gyeong's mentor, Teacher Jung-hwa, died shortly before she was scheduled to hold a disciplinary committee against PI HAN-WOOL (Cha Woo-min), convincing everyone that Han-wool and the Yeonbaek Gang will stop at nothing to silence anyone who threatens their control. Fearing that history is about to repeat itself, Ga-min and the others resolve to protect Han-gyeong at all costs while Detective NA TAE-MAN struggles to gather enough evidence before another crime occurs. As the disciplinary committee approaches, Han-wool launches his final move. His backup fighters surround the school, intending to prevent the hearing and eliminate anyone standing in his way. While Han-gyeong refuses Detective Na's request to flee, believing that abandoning the hearing would only strengthen Han-wool's grip over Yusung, the study group secretly prepares a coordinated plan. Instead of relying solely on Ga-min's strength, every member is assigned a role, proving how much they have grown together since the group was first formed. Chaos erupts when Han-wool's followers invade the school. Lee Joon, Ji-woo, Hee-won, and Se-hyeon each confront opponents using their own abilities rather than depending entirely on Ga-min. Se-hyeon outsmarts stronger enemies with careful planning, Ji-woo overcomes the students who once terrorized her, Hee-won finally casts aside her fear and fights alongside her friends, and Lee Joon protects the others despite being heavily outnumbered. Their teamwork keeps Han-wool's forces occupied long enough for Han-gyeong and Detective Na to continue exposing the truth. Meanwhile, Ga-min reaches Han-wool for the decisive confrontation. Their battle becomes the culmination of everything that has happened throughout the semester, with Han-wool relying on overwhelming brutality while Ga-min fights to protect the people who believed in him. During the intense duel, Ga-min unleashes several of his uncle's forbidden techniques, finally matching Han-wool blow for blow. Although Han-wool refuses to admit defeat, his influence begins collapsing as Detective Na's investigation, witness testimony, and the committee proceedings expose the corruption surrounding the school and the Yeonbaek Gang. With Han-wool's control finally broken, peace slowly returns to Yusung Technical High School. Han-gyeong remains as a teacher, determined to rebuild the school into a place where students can genuinely pursue their education without fear. The study group, once dismissed as a collection of hopeless students, proves that trust, perseverance, and learning can overcome violence. In the closing moments, the friends gather together to study once more, reflecting on how far they have come since Ga-min first dreamed of forming a study group. The season ends on a hopeful note, leaving the future open while celebrating the friendships and personal growth that changed every member of the group forever.
