Baek Z Young, Lim Won Hee, Jung Seok Yong, and Oh My Girl's Mimi appeared as guests on the September 20 broadcast of MBC's 'Radio Star', sharing their stories with viewers. 

On this day, Baek Z Young revealed that she became a big fan of Mimi after watching the variety program 'Earth Arcade'. Baek Z Young complimented the idol by saying, "She definitely has her own uniqueness. It seems like she doesn't understand or doesn't know what's going on, but then she always drops a decisive blow that makes me laugh. And of course, her lips. Her lips are the cutest." 

Here, the MCs observed, "You two have similar lips." Shying away from the compliment, Baek Z Young asked Mimi, "Are yours natural?". 

Mimi coolly replied, "Ah no, I mean don't we all get a few fillers now and then? Although it's been a while [for me]." MC Kim Gu Ra pointed out, "Your lips were already on the full side to begin with, but you gave it some emphasis." Mimi agreed and said, "I filled out the shape." As a great fan of Mimi's lilps, Baek Z Young again stated, "I love that plump upper lip. It's so cute." 

Later on, Mimi discussed her role as an MC for the dating reality show 'Heart Signal 4'. She confessed, "My first and last dating experience was when I was 17-years old. It lasted 50 days. But apparently, 50 days don't even count as dating experience. It ended because the guy cheated on me." 

She then added on, "I don't think dating fits my lifestyle right now. I don't like the process of going from a 'some' to a relationship either. It involves too much emotional strain."
