Gugudan
Jellyfish Entertainment group Gugudan made it’s debut as a 9-member group, which included 3 of Produce 101 participants. The popular Kim Se Jeong (who finished 2nd in Produce 101) is part of Gugudan, together with Kang Mi Na (who also debut with I.O.I) and Kim Na Young. However, the group already made headlines for the wrong reasons even before debut; where they were accused of many counts of plagiarism for their logo, greetings, and even choreography.
