The turning point came from YouTube content. Member Won's personal channel, "Hello, this is Won, nice to meet you," was opened in February 2026. A scene where Japanese member Minami inadvertently greeted viewers by saying "Geoje, yay!" went viral and drew laughter, and this phrase quickly spread as a meme in the form of "OO yay." The channel's producer immediately released a series of follow-up contents highlighting each member's character. Content featuring Won, who is from Geoje, and Jena, who is from Gyeongju, speaking in dialect in Seongsu-dong, as well as content featuring Liv and May appearing as a clumsy duo (Lit and Matt), successively boosted viewership.
