Ahn Ji Young opened up about moving on as Bolbbalgan4 without Woo Ji Yoon.

At the showcase for 'Puberty Book II - A Flower The Butterfly Has Seen' on May 13, Ahn Ji Young introduced her new mini album, saying, "It's late in spring, but I wanted to give listeners the emotions of the 'Puberty Book' album, so I ended up releasing the second part. To be honest, I did feel empty and like the space [Woo Ji Yoon] left was big, but I prepared with everything that I could do."

She continued, "For this album, I tried to bring back the feeling of the past album too. Rather than doing something as a solo artist, I wanted to show a new sound that Bolbbalgan4 is trying out."
