Wow, I can't believe this is my first post here. Anyway, I surely do hope Kara can read this but I guess not.
I believe in Kara, I believe they are human beings who make mistakes as well just like me and billions of other living on this planet. I realized the reason why they were having a rough time during the recording of this show because they have been away from the Korean Media Scene for a very long time and also they were adapting to the Japanese Media Scene.
Also, their emotional well-being must have been extremely delicate due to fatigue and stress. I mean I don't know them that well to make more assumptions, I just hope they are taking care of themselves and just stay happy. I believe those are the most important things for Kamilia.
