Hello! Cloudz is the trio of Eunseok Sungchan & Anton. The name originates from 구룸메즈 (=ex roommates) shortened into 구름즈 (=cloudz). Why ex roommates? Because these three used to live in the same dorm together before debut😆 You can see a little snippet of them living tgt in Rise&Realize Ep 1 before they moved to a new dorm. Anyways regardless of the origin Kfans think the name Cloudz suit them very much since they are all tall over 180cm (hence they reach the clouds~). TMI but this is my only favourite trio hence I only ever talk/post about them❤️
