The rapper carefully examined her own lyrics one more time before the official recording process began, checking for ways to improve them. Confident that there was nothing wrong with her lines, Jessi rapped in front of J.Y. Park, mixing in some English here and there. 

J.Y. Park took issue with the English portion of her lyrics, advising her, "I think it's best to [rap in] Korean. This program is watched by Korean people all over the country so the content must be easy and understandable."
