The song Solo tells about a person who lives alone and he is confident and proud of it. Even after breaking up with his lover, the person in this song still doesn't believe in himself. About the solo song, Jennie said "Many women are in a relationship where they sacrifice many things to be loved by others. But even if they try, they will still make pain. This song talks about being free rather than being a bad person," she said. In the Solo video, Jennie plays a girl who is fragile but gentle and a strong and independent woman. His contrasting images and unique appearance caught the attention of fans to watch Solo's MV. The release of the Solo song, made Jennie the first Blackpink member to release a single. "It's not that we are working on a project after I was chosen. All members will release their own solos. It feels like we are all ready and starting together," he said.
