They are oh my girl. They are originally 8 member group but due to hate and anti-fans overreaction, Jine was diagnosed with anorexia and she ended up terminating her contract with the company and the group as well. They are really talented and their music is spectacular. They are called Idol of Idols because lots of kpop celebrities are their fans including IU, Twice, Exid Hani, Lovelyz BabySoul, 9 Muses and many more. Seunghee, their main vocal is a friend of BTS V and Jimin. They are under WM Entertainment which supervises B1A4, ONF, I (previously), and Izone's Chaeyeon.
