Former Main Vocal
Kim Youjin, KNK’s original main vocalist and the eldest member, is known for his delicate yet stable “honey voice.” Quiet and introverted, he delivers hilarious, sharp comments to the younger members. He dislikes physical contact and curls up when hugged, yet his affection for the members runs deep. After leaving the group, he streamed games casually on Twitch. He’s the charming big brother with a mix of warmth and deadpan humor.
