On March 19, the girls of LOOΠΔ made a guest appearance on MBC FM4U radio broadcast 'Ji Suk Jin's 2O'clock Date'!

During the broadcast, Ji Suk Jin asked, "Which member joined first, and which member joined last?" HyunJin raised her hand and answered, "I joined very first, and Olivia Hye joined last." Here, Olivia Hye added, "I was a trainee for exactly one day. After training that one day, I debuted. I had seen HyunJin unnie on TV before, and then we debuted together so it was very cool." 

DJ Ji Suk Jin also brought up the topic of LOOΠΔ's grand-scale debut project, estimated to have cost approximately 9.9 billion KRW (~ 8.8 million USD). Chuu joked, "Most of it was probably used to feed us." 

When asked how much each member of LOOΠΔ eats, Chuu responded, "One whole chicken per person, plus [a serving of] tteokbokki [per person]... One time before we debuted, we ate 40 servings of meat in one sitting."
