Zodiac Sign: Virgo (Western), Boar (Eastern)
From: Incheon, South Korea
Agency: Fantagio Entertainment
Position(s): Main dancer, lead vocalist, visual/face of the group (Daniel is probably the official face of Wanna One, but Seongwu also had a lot of activities and was probably pushed as the official visual)

Produce 101 Final Ranking (Episode 11): #5
Notable Produce 101 Performances: Sorry Sorry (Team 2), Get Ugly, Never, Hands on Me

Claim to Fame on the Show: His super keen variety sense.  He always managed to make himself stand out every episode.  He also had a lot of catch phrases and bits, like clapping the slate and saying things like “Really super extremely awesome wow thank you” (rough translation) whenever he made Top 11.

Before appearing on Produce 101, Seongwu did a lot of part time modeling, like for this wedding hall. He was also training with Fantagio’s new actor group Surprise U.  He did one short film for their debut project, and also appeared in a scene in their web drama. Seongwu returned to Fantagio Entertainment after Wanna One’s disbandment and has probably had the most diverse amount of activities out of the former members. While he has primarily focused on acting, he has also appeared on variety shows (most notably as a cast member for Traveler), done a lot of magazine photoshoots, and released some music.
