The other day, the agency updated on her condition through the official fan cafe, writing, "Member JinE, about whom a lot of fans are concerned, is currently dedicated to recovering her health at her hometown where her parents are residing. JinE is dedicated to her treatment and is asking for a lot of support so that she can stand before you all with a healthy image once again."
Regarding the absence of JinE's birthday in the girls' 2017 season's greeting, the agency said, "We apologize for making the fans who purchased [the season's greeting] uncomfortable because we failed to be attentive. We are making additional stickers for the missing portions and the written errors and plan to ship them out."
Also, back on December 11, the girls were shooting a CF for a chicken brand and, during a live internet broadcast, said, "Member JinE is not in good health, so she is resting at her parents' home. She's diligently making a recovery."
