they didn't provide any timezone seems to me it's KST by default, the way i understand is 12AM is gonna be the MV release while the whole album release is on 6PM? idk at least that's the way i interpret it. I really don't know how JYP groups but maybe i'm putting thought to it too much. maybe it's the same as TWICE? they're the only JYP group that I stan that can be of reference regarding to this.
