Everyone frolicking through the flowers and having fun...
Though, why is everyone frolicking and laughing?
That's an everyday occurrence here in Heaven..
Well...
Their heads were always in the clouds, weren't they?
The phrase Angel-san uses is "頭の中がお花畑" or "there's a flower field in your head", meaning someone is too carefree or easygoing. The English equivalent of this would be "your head's in the clouds" or "you're off with the fairies".
