Queendom' is currently a hot issue among netizens, and the PD for the show had revealed that if 'Queendom' did well, it was highly likely that 'Kingdom' would also be launched. Now that 'Queendom' is doing so well, it looks like 'Kingdom' may actually be launched.
Road to Kingdom is a survival music competition that features Pentagon as one of the contestants. Pentagon has some amazing performances on RTK, and it's fun to watch.
Road to kingdom is the prequel to the upcoming show Kingdom. The winning group of road to kingdom earns a place in kingdom.
They have a similar setup.
In both the shows artists/dancers will compete. And in the meanwhile people come to know the artists/dancers better and (maybe) they'll see a new side of them.
Road to Kingdom is the sequel to Queendom and therefore also shares a similar format to We Are Blazing.
Similar concept survival shows for already debuted boy idol groups that are looking for more recognition.
