On September 19, Hong Suk Chun shared some photos to his Instagram of the group, as well as a shot with BoA herself.
Each episode of “Hidden Singer” features a famous singer and several impersonators who take turns singing lines of songs from behind curtains. The audience and panel have to try to figure out which one of the contestants is the real singer.
As Key is known as a huge fan of BoA, it will be particularly interesting to see if he can pick her out from all the impersonators!
BoA’s episode of “Hidden Singer 4” will air on October 3 on JTBC.
