Na I-soo is a legendary delinquent who inherits Balhae High School from his late father — the same elite school he despises. He transfers not to study, but to destroy it. Standing in his way is Han Ba-tang, the fiercely principled student council president from a poor family who refuses to let the school she loves fall apart without a fight.
What starts as open warfare between the delinquent chairman and the idealistic student council president slowly turns into something neither of them expected. As I-soo disrupts the school’s polished order and Ba-tang scrambles to hold it together, the two begin to change each other — and realize that the school worth saving might be worth fighting for together.

Spoiler Warning — This section covers the full finale of The Chairman is Level 9. Stop here if you haven’t finished the series.
I-soo makes the choice that matters. Episode 12 opens with the ownership battle fully in the open — I-soo’s uncle Na Jun has aligned with the external parties trying to strip Balhae of its independence, and the legal pressure is real. But the I-soo who arrived at Balhae to burn it down is not the same person who shows up for the final fight. After twelve episodes of watching Ba-tang, the students, and even the teachers pour themselves into this school, I-soo has quietly, stubbornly started to care. He chooses to protect Balhae — not for his father’s memory, but for the community that formed around him despite everything.
The antagonist falls, but the victory is bittersweet. The faction trying to take over Balhae does face consequences — the scheme collapses and the key figures behind it are exposed. But the resolution feels slightly underpowered; the karma arrives on schedule without the full weight the buildup promised. This is a known limitation of the show’s compressed format: 22-minute episodes leave little room to let consequences breathe. Dae-hee also quietly handles the Se-ra situation off-screen, which fans noted as a missed opportunity — the relationship between those two deserved more screen time than the finale allowed.
I-soo and Ba-tang finally close the distance. The romance landing is the emotional payoff the series was building toward, and it earns it. I-soo, who spent the first episode making Ba-tang’s life deliberately difficult, ends the story choosing her — and choosing the school — with no caveats. Their relationship works because neither character compromised who they were to get there. Ba-tang never softened her principles and I-soo never pretended to be someone he wasn’t. What changes is the direction they aim all of that stubbornness.
What it all means. The Chairman is Level 9 is ultimately a story about what happens when someone who has given up on belonging — on family, on institutions, on the idea that any of it can be worth saving — is forced to stay long enough to find out he was wrong. I-soo came to Balhae to settle a score with a dead man. He left as someone who had built something worth keeping. The school was never the villain — and neither, in the end, was he.
✍️ KDramaWorlds Editor’s Take
Our honest read on why this drama is worth your time — and who it’s for.
The premise sounds like a hundred other school dramas — bad boy meets good girl, chaos ensues, romance blooms — but The Chairman is Level 9 earns its charm through specificity. The hook is genuinely clever: a delinquent inheriting the school he wants to destroy is a premise with built-in conflict and built-in character arc, and the show knows exactly how to use it. Moon Seong-hyun plays I-soo with a convincing mix of menace and vulnerability, and Kim Si-gyeong’s Ba-tang is one of the better female leads in recent school dramas — principled without being self-righteous, warm without being passive. The 22-minute episode format works in the show’s favour too: it is almost impossible to get bored when the episodes move this fast.
Where the show is less tidy is in its supporting threads. Dae-hee and Se-ra are set up with enough intrigue to carry a subplot, but the finale shortcuts their resolution in a way that feels like a budget cut mid-production. The consequence arc for the antagonists is also thinner than the setup deserves — the karma arrives, but without the satisfying weight that a 40-minute episode could have built toward. If you are the type of viewer who needs every thread tied neatly, prepare for mild frustration. If you are willing to let the leads carry the weight, the central romance more than compensates. For fans of Business Proposal or Crash Course in Romance, this sits in a comfortable sweet spot of fun, fast, and light on consequences.
The Chairman is Level 9 is not trying to reinvent the school rom-com. It is trying to deliver one well, within a small runtime and a limited budget, and it largely succeeds. The leads are good, the comedy lands, and the central transformation — a character who came to tear something down and ends up choosing to build instead — is handled with enough sincerity that it does not feel earned by accident. It is the kind of drama you put on at eleven at night planning to watch one episode and finish at two in the morning.
