Stray Kids' vocal team, excluding Jeong-in, performed 'As If It's Your Last' and finished without any mistakes. YG vocal team performed a remix version of Wonder Girls' 'Why So Lonely' and overall received high praise. On the dance battle, Stray Kids performed an original and unique stage while YG trainees performed and got compliments and some tips from Park. Few days after the third mission, Park invited Stray Kids to a brunch and revealed the next mission—a busking event. They then went to Hongdae, Seoul to research about busking. The members prepared for their upcoming busking event while Jeong-in and Felix were preparing hard for them not to be eliminated.
