CIX’s Hyunsuk Joins Study Group 2 as Main Villain

CIX member Hyunsuk is officially joining the cast of Study Group 2, adding another idol-actor name to one of TVING’s closely watched youth action franchises. The casting was confirmed after a report said he had taken the role of Ji Young Hyun and had already begun filming for the new season.

According to TVING’s confirmation, Hyunsuk will appear in Study Group 2 and is currently on set. The role is a notable one: in the original webtoon, Ji Young Hyun is presented as the season’s main antagonist, making the part more than a brief supporting appearance. For viewers who followed the first season, the announcement points to a sharper conflict as the series expands its story world.

A Villain Role In A Proven Webtoon Adaptation

Study Group is based on the popular webtoon of the same name and centers on Youn Ga Min, played by Hwang Minhyun, a student who wants to become academically successful despite being far more naturally gifted at fighting. Set at a school known for its harsh environment, the story follows Ga Min as he forms a study group and tries to survive both the pressure of college entrance exams and the violence around him.

That unusual mix of school-life comedy, exam anxiety, and action helped the drama stand out in a crowded youth-series market. Rather than presenting school achievement as a simple coming-of-age goal, Study Group uses the classroom as a battleground, where ambition, loyalty, hierarchy, and physical confrontation all collide. A central villain can therefore shape not only the action scenes but also the emotional stakes around Ga Min’s group.

Hyunsuk’s character, Ji Young Hyun, is expected to occupy that pressure point in the second season. While full plot details have not been released, the original material’s description of the character as a major antagonist suggests he could become a key force pushing the new season’s central conflict forward. For an actor building a screen portfolio, a villain role in a recognizable title can be a useful showcase because it demands presence, restraint, and a clear command of tension.

Hyunsuk’s Acting Profile Continues To Grow

Hyunsuk debuted with CIX in 2019, first becoming known to fans as part of the group’s performance lineup. He began pursuing acting work in 2021, joining the growing list of K-pop artists who move between music stages and scripted projects. That transition is increasingly common in Korean entertainment, but it still depends on selecting roles that give performers a reason to be seen as more than celebrity casting.

The timing of the Study Group 2 news is also significant because Hyunsuk recently signed with Management Run. The move has coincided with a broader push into acting, including his planned appearance in tvN’s upcoming drama My Bias, My Boss. That project also links him with Cha Woo Min, who is connected to Study Group 2, giving Hyunsuk more visibility across youth-oriented drama spaces.

For TVING, adding Hyunsuk gives the second season another built-in point of interest for K-pop fans while keeping the focus on the drama’s webtoon-rooted story. The first season found an international audience, ranking in the Top 5 across more than 140 regions on Viki. That reach means the follow-up is likely to be watched not only by domestic viewers but also by overseas fans tracking the cast, the source material, and the next stage of the story.

The casting also reflects a broader industry pattern in which streaming dramas and webtoon adaptations provide younger performers with roles that can travel quickly across fandoms. A series such as Study Group already has a recognizable premise, a defined visual world, and a genre blend that works well for short clips and global platforms. Bringing in an idol with an existing fan base can amplify that attention, but the long-term impact depends on how convincingly the actor fits the role.

What The Casting Means For Study Group 2

At this stage, TVING has confirmed Hyunsuk’s participation and ongoing filming, but further details about the second season’s release schedule, full cast dynamics, and episode rollout remain to be announced. The key takeaway is that Study Group 2 appears to be positioning Ji Young Hyun as a major obstacle for Youn Ga Min and his allies, which should give the new season a clear dramatic engine.

For Hyunsuk, the role arrives at a moment when his acting career is becoming more visible and more deliberately structured. For Study Group 2, it adds a fresh face to a franchise that already proved it could reach viewers beyond Korea. If the series uses Ji Young Hyun’s antagonist role effectively, the casting could become one of the defining elements of the new season rather than a simple headline addition.
