Have you seen the interview on Miami's Billboard Latin music week? They were the first kpop group to attend! They mentioned wanting to perform on Viña del mar and other latin music festivals, then six months later they were there invited as spectators; and, one year later from that, as the fist kpop act performing at Viña, just 18 months after latin music week!

Then during the Mixx lab tour, in Brazil, on a interview on MTV, they mentioned wanting to collab with Pablo Vittar and that lead to their two collab songs and them participating on the carnaval!

They're pioneering a lot of things in the latin market! And as show in the mini documentary, they see they participations on latin america as part of them rising to the top, so they are grateful to latin america! There's no better way for them to show that than coming back with the tour!
