When I was trying to recall the names of members of Kep1er, I remember Youngeun was the only one I couldn't remember. But I never have seen anyone else express that she seems to be the least known member.
The other ones: Chaehyun, Bahiyyih - everyone knows them
Hikaru, Yujin, Dayeon, Xiaoting, - almost everyone knows them
Yeseo - I remembered her cause I knew she used to be in Busters
Mashiro - I just remember there's a person named Mashiro in Kep1er
I think Youngeun ranked #4 or something in GP999, I'm guessing she is known for being good at singing/dancing to people who watched the show. But I feel like she is the least known member to the average person, I think she has the weakest image and she is also the only member that I wouldn't recognize if you showed me a picture of her.
