In January 2016 it has been reported that Dahye fell from the stairs, fracturing her ankle and right arm, and needed time to recover; YNB Entertainment stated that Bestie’s comeback has been pushed to give Dahye time to get better. It was announced that Bestie would be coming back in May with mini-album or first full album, which ultimately never happened. In summer 2016 Uji participated in JTBC reality singing competition Girl Spirit, where she finished in the third place. The group’s last performance was on December 16, 2016 at Military Year End Concert.
On September 5 2017, YNB Entertainment announced that Uji and Dahye would be leaving Bestie while Hyeyeon and Haeryung would be continuing as a group, with the possibility that new members would be added. That month, it was also confirmed that Hyeyeon would be appearing on the idol competition program The Unit. She was eliminated from the show in episode 13 with her final rank being 27.
After it was no longer possible to access YNB Ent. official website, rumours about the company’s bankruptcy started circulating online. In September 2018 Star Entertainment opened official Instagram account, as well as fancafe, for their new artist Kang Hyeyeon, which concluded the fans’ suspicions about the group’s disbandment without any official statements from YNB Entertainment.
