On the March 31 airing of 'School Rapper', the finalists prepared for their final match. The topic for the stage was 'letter'.
Mark decided to write a message or a letter to fellow high schoolers. While in a discussion about the final stage, Mark's mentor Xitsuh asked Mark if he ever struggled due to the stereotype against idol rappers.
Mark answered, "Honestly, I felt it a little in the beginning. It was hard because of that perspective." And he added, "That made me practice harder and changed my mindset."
