Intro. At this time Big Hit Music (HYBE) were looking for more talents so they gathered four girls (three Korean girls and one Latin Korean) so now they had to train them to be idols but each one already had experience in singing and dancing they just had to perfect everything, then the right ones to train them would be the BTS the most recognized kpop group around the world and their fandom Army the most powerful in the world, They made a show full of Run etc videos called "Trained Idols" on the show run by (Kim Namjoon, Seokjin, JHope, Jungkook, Jimin, Taehyung, Suga) and the girls to train are (Joy, Mihee, Yoona and the Latin Korean girl Lizzy). So everyone lives in a big mansion where everyone has their rooms except us girls we had a big room where we all had our space, our beds and our closets, but if we had to share the shower, even though it was big, it was only one shower and there was also a shower .
