During the episode, Dongmakgol Girl secured her spot as the 83rd generation Mask King, and Hani was forced to unmask, revealing herself as none other than Wonder Girls' member Sun. The former idol halted activity after getting married in 2013 and has since given birth to two children.

When talking about her new life as wife and mother, she joked that if she tries singing along to idol songs around her kids these days, they tell her to knock it off.

Sun added that when she first arrived to the broadcasting station, she got nervous as it reminded her of her early days as an idol. She then expressed gratitude to VIXX member Ravi, who was appearing as a panelist, after he expressed how big of a fan he was.
