A.M (에이엠)

Seong Hyun Woo, who performs as A.M, is a South Korean rapper, dancer, and vocalist who came to wider public attention as a contestant on the competitive reality series *Produce 101 Season 2* before serving as leader, main rapper, and main dancer of the group Limitless.

Produce 101 & Early Career

A.M's first significant exposure came through *Produce 101 Season 2*, Mnet's high-profile elimination survival series that drew millions of viewers and produced Wanna One. His appearance on the programme placed him in front of one of K-pop's largest broadcast audiences at the time, and it formed the foundation for his subsequent group activities.

Following the show, A.M took on the role of leader within Limitless, where he held the dual distinction of serving as both main rapper and main dancer — a combination that positioned him as one of the group's primary performance pillars alongside his vocal contributions.

Recent Activities

In early 2026, A.M shared a personal account of a serious assault he experienced while attempting to intervene and stop an acquaintance from driving under the influence of alcohol. He was hospitalised following the incident due to severe bleeding. He disclosed the events publicly through his YouTube channel in a video titled *Story of Being Assaulted While Stopping Drunk Driving*, speaking directly to his audience about the circumstances. The disclosure drew attention beyond the usual scope of music coverage, reflecting the platform he has built outside of traditional group promotional activity.
