Hahyun, a practical dance department graduate from Korean Arts High School; at the request of his uncle, he became a stand-in for an idol audition program, Survival ID. As originally planned, Hahyun received the “edited,” “invisible,” “rapid fail” ending, but was able to survive every stage with the help(?) of fans… ‘Uncle, I want to get off… TT' Hahyun, who once loved dancing injured his body, and abandoned all his dreams. "Since I gave up, what is this reality that debut is nearing again?" “Sunbae, I like your dancing.” Besides, where did the participant ‘Jigu’ who knows Hahyun’s past come from?!
