So here it is:
Quote from Incognito-ayu:
Very roughly (sorry!), Ayu say that because it was a beautiful sunshine and weather, she was walking to the Studio. She says that if she has her mouth opened, it's because she's singing!
The pic in the studio shows the moment when everybody say "Finish! yeaaaah" !
And the last one is for the wonderful hairstyle of the famous Kome!^^
