The Uncle Who Taught Forbidden Fighting Moves Is Here — Kwon Sang Woo Joining Study Group 2 Is the Best News of the Week

If Season 1 of Study Group already had you hooked, Season 2 just raised the stakes dramatically. Korean entertainment legend Kwon Sang Woo has officially been confirmed to join the TVING series — and the role he’s playing is exactly the kind of warm, complicated, quietly badass character that turns a great show into an unforgettable one.

Study Group 2 — Key Details

What Is Study Group About?

Based on the popular webtoon of the same name, Study Group is a high school action-comedy about Youn Ga Min, a student who dreams of excelling academically but is only gifted in fighting. At a high school notorious for being one of the worst in the world, he forms a study group and dives into the ruthless world of college entrance exams.

It’s the kind of delightfully absurd premise that only action-comedy can pull off — fists flying in the hallway, textbooks open at the desk. Season 1 was a genuine global hit: the drama ranked in the Top 5 for over 140 regions on Viki, proving its enormous international appeal.

Kwon Sang Woo’s Character — The Uncle, the Mentor, the Legend

Kwon Sang Woo will take on the role of Jeon Young Ha, Youn Ga Min’s uncle who taught him “forbidden fighting techniques.” Though he was ultimately cut off by his sister for secretly training his nephew, he stands out as a warm and deeply human character who remains by Youn Ga Min’s side, offering support and guidance.

Let’s take a moment to appreciate just how perfect this casting is. Kwon Sang Woo — a man who built an entire career on charisma, physicality, and an ability to be simultaneously hilarious and genuinely moving — playing the rogue uncle who gave his nephew skills he was never supposed to have? That’s not just good casting, that’s inspired storytelling.

The detail about being cut off by his sister for secretly training Ga Min adds so much texture to this character right away. He’s not the stern mentor or the comic sidekick — he’s the person who believed in the kid when the rules said he shouldn’t, and paid a personal price for it. That’s the kind of character you root for the entire season.

Why Season 2 Is Already Shaping Up to Be Bigger Than Season 1

Following Season 1’s global success, production for Season 2 was confirmed with filming already underway since last month. The swift return is a testament to just how deeply Study Group connected with audiences worldwide — and with Hwang Minhyun reprising his breakout role alongside a legend like Kwon Sang Woo, the chemistry between uncle and nephew is going to be one of the season’s most watched dynamics.

Hwang Minhyun’s Ga Min has always been defined by his fierce determination dressed up in complete academic mediocrity. Now, meeting the man who shaped his fighting ability — and who’s been absent from his life as a result — gives Season 2 an emotional backbone to go alongside all the gloriously chaotic action.
