This is of no fault of the girls or guys in each group, but these are groups that I think have one or two members that are much much more popular than the rest.
What do you think?
Seolhyun - She suddently burst into stardom with 'Like A Cat' and is now thought to be the next Suzy. She seriously has ads for EVERYTHING and is one of the most famous girls from a girl group in Korea right now.
2. Block B
Zico - Zico got huge after the success of Block B as well as his solos and all the songs he's written or produced. Now he's one of the biggest names in Kpop in Korea and he advertises pretty much everything just like Seolhyun.
3. A Pink
Eunji - After Reply 1997, Eunji became a household name. Before that, A Pink was just a normal girl group that wasn't necessarily huge, but thanks to Eunji (and now Naeun's appearance in Psy's new MV) A Pink is much much more popular.
Eunwoo - From debut he was known to have a gorgeous face, but after a great performance in his recent drama, he's EVERYWHERE. He's the spokesmodel for Baskin Robbins (which is huge in Korea) along with a million other ads he's featured in. He's making bank!
Hyuna - I think this is the most obvious one. Hyuna was much more successful as a solo artist (not to blame the girls of 4minute, if anything i blame cube but thats another story...) Luckily 4minute has always been super close so I know they dont hold any grudges towards Hyuna for her fame.
6. Miss A
Suzy - Honestly, many people just getting into Kpop don't know that Suzy is/was in Miss A. She is so huge for her acting and her commercials that it's easy to forget. She's the absolute queen of advertisements in Korea.
