Weeks ago, YUI’s next single was confirmed to be released on August 10th.
Today CDJapan confirmed the information, but the status of the release date appears “postponed”
My guess is they are waiting for YUI’s concert in Hong Kong to make the information public. The new heartrending song might be played that day.
Hopefuly they will start promoting as soon as the concert is over, since Scandal, Stereopony, ZONE and other artists have already confirmed their releases for the same date, the race already started.
