The actual show ‘school attack’ is ran on the dingo YouTube channel so no this one wasn’t by hanbin’s company 😭. Hanbin’s company studio gl1de own a channel called studio peanut butter that does something very similar but it’s not called school attack and it’s not just limited to schools, I’m really suprised zb1 hasn’t appeared there yet though because multiple big groups like enhypen, aespa ect have been on it and i definitely think they would offer zb1 the chance to go (because if hb)
