Hard working queens did that! It's a reflection of their popularity and how hard they promoted since debut. Three Korean comebacks and three japanese comebacks already this year!

This girls work their ass off since debutt... Multiple concerts, debut in Japan, another tours, and they still got their lessonss.. And they just debut 3 years ago...

When people bash them and compare them to another girlgroup, I was like whats the point.. I think is kinda harsh..

They debut as an idol which more likely sell "concept" and being likeable.. You can get amazing singers all across the globe.. But idols is not about amazing sing skill only, if your group cant accepted by people.. Then its doomed..

They are lucky with song cheer up which get them have morrreee massive popularity.. But they also consistently promote their group.. And applause to their marketing team.. Or whatever team behind them..
