Hi, why 9012? I’ve seen a lot of post about that number in runningman I just started watching them.. currently on ep 228

Aah it was first 7012 in episode ep.276 it means Seven members always together (or something like that, I’m bad remember exact words). And now in newer episodes they said 9012 so nine members always together :’)
