Somi is bilingual right? She speaks fluent english and korean?
Also, I know her role is center/lead vocal. I am just wondering, what does center mean? Like is she in charge of being the point of most of the formations during the performances and being a visual of sorts? I am kind of lost in this regard. I.O.I is the first group I have personally heard to have a center so, I am just confused on what her job is as being the 'center'? Help please?
