@ojou it wasn't a survival show where 100 hopefuls compete for public votes to make it into a group.
Instead, an agency had given one of their trainees (Bang Chan) permission to form his own group from the trainees currently at the agency.
Then they would have to demonstrate to their boss that they were all good enough to debut as a group. And if he thought any one of them wasn't good enough, the boss eliminated them.
It was ... fucked up.
They all became my sons at that point.
