The members of Black Pink went through 4 -6 years of training under YG Entertainment. On the July 26 airing of 'Kim Shin Young's Hope Song at Noon', Jennie, who trained for 6 years, revealed, "I wondered if we could really make our debut. Our debut got delayed a lot. The preparation process got extended. I wondered, 'Would we really be debuting? Would we ever be coming out?'"
Jennie also talked about the concepts she wants to try. She said, "We took on a bright, cute concept for 'As If It's Your Last'. Next time, I want to try a really strong concept with a 'girl crush' vibe."
