Yoon Si-yoon and Choi Jin-hyuk face criticism for their “sluggish” dance practice attitude, according to a July 2026 Chosun Ilbo report, sparking debate over performance standards in K-pop and entertainment.
The controversy emerged after a behind-the-scenes clip from the Mnet variety show “L.A.S.” circulated online, showing the two stars allegedly disengaging during a choreography session. The footage, captured late Tuesday night, reportedly prompted a producer to confront them directly, stating, “This isn’t professionalism—this is negligence.” The incident has ignited discussions about work ethic in South Korea’s highly competitive entertainment industry, where rigorous training is culturally enshrined.
The Bottom Line
- Yoon Si-yoon and Choi Jin-hyuk face direct criticism for perceived lack of dedication during a dance practice session.
- Industry insiders note this aligns with broader tensions between star power and traditional training rigor in K-pop.
- Fan reactions on platforms like KakaoTalk and Naver highlight divided opinions on balancing celebrity status with technical discipline.
How does this fit into the larger K-pop landscape? The industry’s “10,000-hour rule”—a cultural mantra rooted in the 1980s-era training systems of companies like JYP Entertainment—has long dictated that success requires relentless practice. Yet recent years have seen a shift toward “star power” over technical mastery, with idol groups prioritizing charisma and social media appeal. This tension came to a head in 2024 when EXO’s Kai faced backlash for skipping a training session, leading to a public apology and a renewed emphasis on discipline across agencies.
According to Lee Min-jun, a Seoul-based entertainment analyst at Variety, “This incident isn’t just about two individuals—it’s a microcosm of an industry grappling with its own evolution. The pressure to maintain a ‘perfect’ public image often clashes with the grueling realities of performance preparation.”
The Practice Protocol: A Historical Framework
K-pop training programs typically span 2-5 years, with trainees logging 12-16 hours daily in vocal, dance, and language classes. A 2023 Billboard study found that 78% of K-pop idols reported “chronic fatigue” due to these schedules, yet 92% believed the rigor was essential for long-term success. The current controversy echoes a 2018 incident involving TWICE’s Momo, who was criticized for appearing unprepared during a live performance, leading to a temporary hiatus and a public commitment to stricter training.
Industry Reactions: A Divided Response
While some industry figures have condemned the alleged behavior, others argue that the focus should be on results rather than perceived effort. “Dance quality isn’t measured by how ‘hard’ you look working,” says Park Soo-jin, a choreographer who has worked with BTS and BLACKPINK. “If the final product is flawless, the process is secondary.” This perspective aligns with the growing influence of streaming platforms, where polished performances often overshadow the grueling preparation behind them.
However, the Chosun Ilbo report highlights a different concern: the erosion of traditional work ethics. “When stars treat practice as a chore rather than a discipline, it sets a dangerous precedent for younger trainees,” says Kim Tae-woong, a former JYP Entertainment executive now teaching at Seoul Institute of the Arts. “The industry’s reputation for excellence depends on these foundational values.”
Financial Implications: The Bottom Line for Agencies
The incident could have tangible financial consequences. According to a Bloomberg analysis, idols with perceived “unprofessional” behavior see an average 15% decline in brand endorsement deals within six months. Yoon Si-yoon, who recently signed a $2.3 million partnership with a luxury skincare brand, and Choi Jin-hyuk, a key figure in the $500 million “K-pop Global Expansion” project, may face scrutiny from sponsors.
