"Girls Next Door" and "Unnie" are 2 groups that she had participated in. "Girls Next Door" is a group made from a mix of other group members. It's a 1 song group that is temporary and a variety show made the same as "Unnie" but "Unnie" is a group made of random famous people who want to be singers or idols but couldn't get the opportunity. So it's a group with a mix of different ages and with different jobs like actress, comedian, and solo singers that is made just to fulfill one of their dreams which was to be a singer or an idol~ Her previous temporary group that has more than 1 song and lasted more than 1 year before she became a solo singer is called " I.O.I". I would suggest you guys react to "IOI". "IOI" is a 11 member girl group made from Produce 101 a survival show.
