YOO HWE SEUNG is a vocalist in N.Flying. He joined the band in 2017 after appearing on Produce 101 Season 2, so his entry date comes after the group’s original Japanese and Korean debuts. His addition helped establish the band’s two-vocalist format.

His singing also appears in soundtrack and collaboration work outside the band. Those recordings should be credited by their actual format, rather than treating every cover performance or television appearance as an independent solo single.

Within N.Flying, his voice works alongside Seung Hyub’s singing and rap. The group’s records and live performances provide the main context for that partnership. Everlasting and Still are group releases, while individually credited recordings belong to his own activity history.
