During the broadcast, DJ Ji Suk Jin asked Yerin about her interest in working with the former contestants of 'School Rapper'. Yerin responded with, "I like programs like that, so I watched with a lot of interest." She continued, "Rap represents another me. To be honest, I've never learned rap professionally and I can't really rap well, but it's still fun."�

She then showed off a little of her own freestyle rap for listeners! Afterward, she shared that her rapper name was MC Moksal ('mok-sal', meaning pork neck in Korean). Because "I like pork neck in my kimchi jjigae", Yerin explained.�
