Friday.
"Rebirth" album release date.
Tang Yiyi ended up booking a convention centre outside the city because it was the only place available at such short notice. All the other places she inquired at were fully-booked.
It was quite far and big for an event called a "party", so she was at first worried that nobody would come. However, she was assured after talking with the Black Stars fan club. Just the people from this fan club alone who confirmed that they would attend the launch party were enough to fill the convention centre nicely without Iris and her team losing face.
In addition to the fan club, there were also quite a lot of individuals who unofficially confirmed their attendance via the online invites posted by JJ's record label on its website and social media accounts.
At the convention centre.
