The girls mentioned former IOI member Kim Chung Ha being the best out of the contestants. Member HyungEun commented, "We didn't realize it at first. But we were moved by the way she danced every time. Her facial expression was different. She could thrive in anything."

When asked the question, "Did you regret not being able to move on to the next level?" Member Genie replied, "Out of the 100 members, we were on camera the most, allowing us to fully express our individual talents. I think they did a good job in editing."

At the remark, "If you were given the opportunity to appear on 'Produce 101' again?" The members responded in unison with "Yes." HyungEun said, "If I were to go on the show a second time, I would present all of my unique styles. I like HyunA's tough but sexy concept." Genie added, "I miss those days. I want to go back to 'Produce 101'."

BULLDOK, consisting of Genie, HyungEun, Kimi, Say, and Sora, debuted with their first single 'Why Not' last October.
