Dia performed her cover of Jeon Won Seok's "Don't Leave" and couldn't help but to spill tears after being immersed into the emotions of the song. She shared during her interview, "I released 18 albums during the past 5 years, but there are a lot of people who don't know... I wanted to perform on the 'Immortal Song 2' stage before I die." She later beat Bada in one round with 378 points.
