The proud idol was none other than MONSTA X's Jooheon! On the second episode of 'SMTM 4,' Jooheon said during his interview, "I'm an idol," emphasizing his point yet again with, "I'm just an idol rapper." When asked what he thought about the perception that underground rappers have towards idol rappers,Jooheon confidently proclaimed, "Sometimes when I hear that, I just want to just say it to their face, 'I'm better than you.'" 

It turns out that Jooheon's words weren't just wind as he heated up the stage with some fierce lines! He ended up passing through, impressing with his stage presence. Tablo pointed out to him that his rap is good, but also advised the idol that he'll have to make sure to bring the best Jooheon in the upcoming rounds.
