On January 18, the YG Entertainment founder wrote to Instagram, "'Mask King' appearance. It's a secret which member and when it'll air." However, he immediately deleted his post due to the spoiler. 'Mask King' relies on the anonymity of the singers, so it looks like Yang Hyun Suk accidentally slipped up.
In other news, iKON are making a comeback with their 2nd full album 'Return' on January 25.
Which member do you want to see on 'Mask King'?
