Gill (musician)

Infinite Challenge (2009-2014)

Gil made his first appearance on an episode which featured Korean figure skater Kim Yuna in April 2009, ostensibly substituting for Jeong Jun-ha, who had to leave the episode recording early. He remained a de facto member of Infinite Challenge until he became a full member later that year. During the Boxing episodes in January 2010, Gil showed off his 9-year-long training in the sport. Gil is often called the Unfunny Friend due to his inability to ad-lib as quickly as the other co-hosts.

The Voice Korea (2012-2013)

With his commentaries, Gil has shown that underneath his rugged hip-hop exterior, he is a warm and rather approachable individual. Consistently offering warm words of encouragement and advice to his disciples to help them ease their anxious hearts, and lightening up the atmosphere with his witty sense of humor, he has become an indispensable personality on the program.^[2]
