I didn't say that Cube was good to them. I'm just saying, they did try. But it wasn't enough. Imo, the problem with CLC was, that they didn't find their own sound. Which obviously is Cubes fault no question. Changing concepts too often, makes it harder to like a group. But if we look at (G)I-DLE for example, even though they change concepts often too, you can still tell it's their own sound. CLC lacked that sadly imo.
As for 4minute. They were lucky that there weren't that many GG's around when they were popular. Once more GG's debuted, people forgot about them and then it became Hyuna ft 4Minute
