For gen 4 groups obviously, Irene and Seulgi was a pretty successful sub unit with such a simple formula. Get your two best dancers from the group, give them an intricate choreography with a dark concept. Example of a pair I can see doing this is possible Yeji and Ryujin from Itzy. Plus it doesn’t even have to be girls, people saw Astro’s latest sub unit draw inspiration from Irene & Seulgi too. What do you think?
Edit: also not anytime soon probably a couples years from now
