Pledis Entertainment announced on April 12th,
"Hello. This is Pledis Entertainment.
We are writing to inform you regarding the health and participation in group activities for the 'Romanticize' comeback of NU’EST member Aron.
Aron has been trying his best to get better since we announced his hiatus this past January due to anxiety. The member was adamant to make this comeback for the fans, so we have been working closely with specialists to supervise his health condition while preparing for this comeback.
Although the artist wanted to participate in all official promotions and activities for the comeback, we have decided that his condition isn't at his best to do so. To prioritize our artist's health, we are announcing Aron will be taking a flexible approach regarding the comeback promotions. We kindly ask for your generous understandings.
We will continue to strive to ensure the health and safety of the artist so that Aron will be able to return healthy to the fans. We will provide updates on Aron's resume on official activities in a separate notice.
Thank you to all of you who are supporting NU'EST's 2nd full album 'Romanticize' promotions. We ask for your unchanging love and support for NU'EST in the future as well.
Get well soon, Aron!
