U-Kiss Release Round and Round First and Second Versions

I didn't really know about U-Kiss release song,so this is just a coincidence.As U-Kiss's fans know,Round and Round is just released yesterday.Instead of that, Round and Round music video have two versions,one is full of dance,and the another have a gimmick.This two versions are released just within a few hours respectively.I've thought,this song is just so-so,but I admit it,I was wrong.Round and Round is overwhelmed myself.I feel the hotness.You should feel it.Catch that on their music videos.
