I can't find this kind of topic so I made it. If there is already topic like this just delete this topic ^^.
My first topic made ^^. So here it goes
At first, I want to say that I don't want to offend anyone with this question of mine ^^. When Kara is still 4 member group, they didn't get good popularity. Seungyeon even say that they didn't make an explosion at that time. But since they comeback as a 5 member group, everything change. From your point of view, why does that happen?
Personally I think because their cute concept when they become 5 member group. But to think about it again, they also become successful with Lupin which is nothing about cute. So, what do you guys think?
