Episode 1 of Study Group introduces us to YOON GA-MIN (Hwang Min-hyun) — a bespectacled, deeply earnest boy with one obsession: studying. Despite pouring everything into his academics, his grades sit consistently near the bottom of the class. Convinced that a study group at a new school is his ticket to university, Ga-min transfers to Yusung Technical High School — a place he's heard is serious about academics. He couldn't be more wrong. Yusung is Korea's most notorious school: students walk the halls half-uniformed, smoke openly, and run an underground student ranking system based entirely on who can fight hardest. The entire teacher staff, including the principal, has long given up.\n\nUndaunted, Ga-min spots KIM SE-HYEON (Lee Jong-hyun), the only student who seems to actually care about studying, and immediately asks him to join his study group. Se-hyeon flatly refuses — for good reason. The school's true power lies with PI HAN-WOOL (Cha Woo-min), the son of a gang leader, who built a student ranking app that runs the school's social hierarchy through fighting. Crossing Han-wool's world means trouble nobody wants.\n\nThen new temporary homeroom teacher LEE HAN-GYEONG (Han Ji-eun) arrives — and Ga-min immediately recognizes her as his old private tutor from years ago, who quit suddenly without explanation. The school administration panics at her presence, a first signal that Yusung's rot runs deeper than bad grades.\n\nThe episode's turning point comes when class bully LEE HYEON-WOO beats Se-hyeon to a pulp over an accidental bump in the hallway — right in front of Han-gyeong. Ga-min steps in, slips on a mask, grabs a fire extinguisher, and pulls Se-hyeon to safety through the chaos. Se-hyeon is furious — not grateful — convinced Ga-min has only made the bullies angrier. But when Hyeon-woo destroys Se-hyeon's study notes in front of him, something snaps in Ga-min. He drops the mask, beats Hyeon-woo to a standstill bare-handed, and demands an apology. It's the first real glimpse of what Ga-min is actually capable of.\n\nTouched by how fiercely Ga-min fought over something as simple as a notebook, Se-hyeon finally agrees to join the study group. The episode ends with two misfits — the boy who can't stop fighting and the boy who can't stop studying — sitting down together at Yusung for the very first time.
