No matter how the Fifty Fifty mess ends, it will never promote in Korea again.
It seems H1-Key has filled FF's gap in Korea, not that FF had any presence in there to begin with. I did not follow H1 Key in detail, but it seems since its music style is kinda closer to FF's,
Right now a member of h1-key is participating in the Queendom Puzzle, and it will probably continue its policy of being a staple in Korean events, but aiming for a potential global hit. In the next comeback, it is possible that the Thai member, who was initially there but left after the group showed no promise, might return and if that happens it is now jumping into the global arena.
Meanwhile it seems CSR is having a shakeup.
It went to Japan and Europe, and while its Japanese perf had little following, although it had a Japanese member, it was quite well received in its perf at Holland and Belgium although the audience was smaller.
CSR is actually quite a bit well financed, since it is owned by Com2us, a game company.
CSR decided to ditch its leader.
That group was formed around the leader, who was the first to join. Everyone else was selected to prop up the leader, and now it will have a change of the leader.
The person standing at the center vs the main vocalist, who is the youngest, are vying for the leader position. While some Koreans support the center, virtually all opinion from its few foreign fan supports the vocalist.
Although the vote seems to be made already (the center would have won at that point), if there is an overwhelming support for the vocalist, who is the only one who can speak English in the lot, they would quickly make another video declaring the vocalist as the leader.
If that happens it means it is abandoning its Lovelyz/GFriend concept, and would gear towards a Fifty Fifty style of music without the mess. It also has a #1 from Music Bank at its belt, legitimizing them. It might also have member changes but that is something I haven't really researched. Most likely the Japanese member, the member who look like Umji and one or two more might be let go.
Whether you like or not, the changes brought by Fifty Fifty will last, and Korea will cease to be the main ground for even smaller acts
