It’s not right ofc. But like the others it’s probably meant to get others emotionally attached to the members, draw attention, and get clicks. It unfortunately sells at the end of the day. Whether it’s done publicly or behind the scenes I’d be surprised if stuff like this isn’t more common than not. If it didn’t work so well I think it wouldn’t be publicized as much but just look at just about any survival show, they’re always pitted against each other, threatened with being cut, sometimes forced to do or say things they don’t want to, and at the end of the day the group gets huge and becomes one of the big, iconic, and followed groups, or at least more than they’d be otherwise. Not always but most of the time, unless the show focuses on more nugu groups exclusively. Unfortunately a sad reality of kpop, especially these days.
