A popular South Korean YouTuber has been found dead just two days after telling fans he was struggling with an extreme lack of sleep. Na Dong-hyun, known online as Dae Library, was discovered in his Seoul home on Saturday, according to local police. The 46-year-old’s friends alerted authorities after he failed to show up for a planned meeting. Police said there were no signs of foul play and no suicide note, adding that they are investigating whether an underlying illness played a role. In a livestream on Thursday, Na told viewers he had been surviving on minimal rest while attending Seoul Fashion Week. “I think I slept for about three hours after getting my hair and makeup done from morning,” he said. That stream, which lasted more than five hours, would turn out to be his last. He chatted with fans and played games throughout the broadcast. Dae Library had more than 1.4 million subscribers on YouTube, where he had been creating content since 2010. He married fellow influencer Yumdeng in 2015; the pair divorced last year after eight years together. Police have not released further details pending an autopsy.
