The countdown ends on his birthday, 18th August, which was also supposed to be the release date of his 2nd solo album. However, this date hasn't been confirmed to be his comeback date yet. G-Dragon decided to produce a high-quality album instead of rushing to a deadline. That's why he didn't set any date in stone so far.
On the other hand, the countdown has made fans speculate that this might a confirmation for his solo album to be ready by 18th August. But he didn't make any explanation on the countdown, so we have to wait and see what will happen on his birthday.
What are your speculations? Is the countdown just set for his birthday or might it also be the release date of his 2nd solo album?
