Kwon Sang Woo joins Study Group Season 2 in a move that has sent the K-drama community into a frenzy, officially stepping into the role of the legendary Jeon Young-ha. This isn’t just any casting choice; Kwon Sang Woo will be portraying the uncle of the protagonist, Yoon Ga-min, played by the charismatic Hwang Min Hyun. Fans of the original webtoon and the first season are already buzzing because Jeon Young-ha is the very man responsible for teaching Ga-min his formidable fighting skills, making this onscreen duo a powerhouse of talent and action.
TVING confirmed the news on April 23, 2026, solidifying that the sequel to the hit series is gearing up to be even more intense than the first. For those who followed Season 1, the story of Yoon Ga-min—a boy who desperately wants to study but is naturally gifted at brawling—struck a perfect chord between high school drama and high-stakes action. Now, with Kwon Sang Woo joining Study Group Season 2, we are getting an actor with an iconic pedigree in the action genre. From his unforgettable performance in Once Upon a Time in High School to the comedic grit of Hitman: Agent Jun, Kwon brings a level of authenticity and “real-deal” martial arts energy that fits the “Study Group” universe perfectly.
