I was shocked when I 1st heard that news. Why did they cut their real hair, because of new singles name?
But.. hairstyle especially to idol girls, It's very important and good to change their images variously.
I think yeah.. they looks fine even in short cut. But I prefer their long hair...
If they want to change their image like new single, they could use wig. Well.. I just hope their hair would become long fastly after that single.
