They could make fans so much more excited if these doors actually opened something like single artwork, single release date, single , music video, track listing, and etc.
So since not all of us are on twitter I thought about making private chat room to discuss ANTIdiaRy in the private so Rih can't watch us : https://niltalk.com/r/z6hSd
R4 is coming on the 8th like I said minutes before R3 was unlocked. There's a system/order to the rooms being unlocked.
R4 - Dec 8
R5 - Dec 12
R6 - Dec 15
R7 - Dec 17
R8 - Dec 18 (Album Release Date) Or At least the single.
The system you are following is the same system we've been following its just that you've shifted everything a day or two over. But essentially you are subtracting a days wait between each room.
