BTOB's Changsub is ready to launch his web reality series, 'Juhn Gwa Ja'. 

Changsub's new web reality series 'Juhn Gwa Ja' is a shortened acronym for "a man who transfers [departments] every day". In the highlight video released on November 8 KST, Changsub was seen going around one university campus to introduce his new web reality series to students from various departments while asking them several interview questions. In one scene, Changsub was even heard hilariously asking a running child what department he is from, drawing laughter.

Changub's 'Juhn Gwa Ja' will be releasing its first episode on November 11 KST.
