Khon Kaen Province, Thailand. As a child, he was nicknamed "Lert", before later adopting the name "Illslick" or "Ill", which became his stage name in the music industry. His parents separated when he was young, and he was raised under the care of his aunt in
Lampang Province. Later, he moved to
Chiang Mai to attend high school, which marked an important period in his life — it was during this time that he began to enter the music scene and develop his skills in songwriting and rapping. == Music career ==
