For those who might not know about fromis_9, they are the winners of Mnet "Idol School". As such, some netizens are also calling the girls from two groups girls 'CJ girls'. This is because Mnet is under CJ.
Both groups look amazing standing beside each other and netizens also are praising their beauty.
Since IZ*ONE's YuRi also took part in "Idol School" but did not make it to the debut group, it is expected that she is close with the girls from fromis_9. In addition, fromis_9's GyuRi also participated in "Produce 48" and might be close to the girls from IZ*ONE. Some fans are also hoping that they could see more interactions in the future.
