Popular Korean YouTuber found dead days after sharing concerning health symptom during livestream

The content creation community is facing another tragic loss this year.

Earlier this year, Los Angeles-based YouTuber P2istheName passed away from sudden cardiac dysfunction.

The streaming world also lost French creator Jean Pormanove, who died in his sleep at age 46 and allegedly ‘tortured’ for ten days before he died on camera.

Now, a popular South Korean YouTuber has been found dead just days after publicly speaking out about his health issues in a livestream.

Na Dong-hyun, better known online as Dae Library, was considered one of Korea's most established YouTubers, building an audience of over 1.4 million subscribers since launching his channel in 2010.

His content spanned commentary, livestreams, and variety-style gaming broadcasts that helped define Korea's early YouTube landscape. However, the streamer was found dead at his Seoul home on Saturday (6 September).

The 46-year-old YouTuber's friends contacted police after he failed to appear at a scheduled meeting and couldn't be reached through normal channels.

According to local outlet Chosun, police and fire officials entered his residence and discovered him already deceased. Authorities have confirmed there was 'no suspicion of foul play'.

“We are considering the possibility of death from an underlying illness and plan to determine the exact cause through an autopsy,” police said in a statement.

In his final stream, Dae Library complained of chest pains and severe fatigue and at one point, he told viewers: “My heart feels a stabbing pain.”

The creator also revealed he was operating on minimal rest, having slept only three hours while attending Seoul Fashion Week before going live for more than five hours.

"I think I slept for about three hours after getting my hair and makeup done from morning," he stated on his stream.

Fans noted he appeared visibly exhausted in recent weeks.

In his personal life, he married fellow influencer Yumdeng in 2015. The couple divorced in 2023 after eight years of marriage.

At a time when streaming platforms were filling up with provocative content, Dae Library carved out a different path. He maintained profanity-free broadcasts and respectful communication, becoming an icon of 'clean broadcasting.'

Fans across social media are now mourning Dae Library, whose influence spanned more than a decade.

"Heartbreaking. Rest in peace, Dae Library," one user wrote on X.

"Rest in peace brother," another replied.

Comedian Kim Daebum also paid his respects to the late streamer.

“This is shocking news. I feel truly hollow. As South Korea’s top YouTuber, he was a very kind and polite person,” he said. “Despite having many subscribers, he never showed off about it and was a truly wonderful person who helped novice YouTubers."
