These three rookie groups, who spent their first years in the industry very productively, have 3 monster leaders who take in charge the burden. I don't wanna call them rookie leader because they are not like rookies, of course there are many ways to go, but it seems that they know where to go and what they want. Don't you think these leaders, who succeeded in proving themselves from their pre-debuts, are they like monsters?
