On MBC "Infinite Challege" that was aired on Saturday, Gil had a mission to hunt vampires as a vampire hunter. On the episode, Gil wore black attire to give off the vampire hunter feeling. Also, he showed a different side of him with tattoo on his face and a black wig. 

The fans after watching the show seems to have grown curious about the hair because the wig looked so natural. They responded on SNS saying "Did  Gill grow his hair?," Is it real?," and "Does he really have hair now?" However, Gil scratched his hair, saying "I'm scratching my hair because of the wig. What kind of vampire bites head?" He revealed that it was a wig. Fans said "I didn't even notice because it looked so natural," "I just noticed the wig," and "how can it look so real?"
