Singer-songwriter BOL4 has again taken over the music charts.

As of 8 a.m. on May 14, "Pum," the title track of BOL4's new mini-album "Puberty BookII Butterfly Insight of Flowers," topped the real-time charts of Genie, Bugs and Soribada, and other major charts including Melon.

"Pum" is an attractive song with the witty lyrics of the chorus and points of the melody line wrapped in the ears, with funky rhythm bass and electronic guitar leading the mood of the song.

In addition, "Blank," a song with BOL4's unique cuteness and loveliness, "Counsling," a song about inner feelings that could not be shown frankly, and "Dandelion," a message of consolation and encouragement for all the youth still blooming, all made it to the top of the list, proving BOL4's dignity.

He then posted official photos of "Dandelion" and album preview videos on SHOFAR Music's official SNS on May 12, opening all the songs listed in "Public Book II Butterfly Insight of Flowers."

"Dandelion" is a song that contains a message of consolation and encouragement for all the young people who still bloom, and can be considered the most ballads in this album.

BOL4, which gave off a pure atmosphere with dim eyes in official photos, also showed off its colorful charm in the preview video of the album "Publicy Book II Butterfly Insight of Flowers," raising expectations for the album.

BOL4, which has shown outstanding competence as a singer-songwriter with all albums written and composed by herself receiving great love, will again target listeners' tastes with a high-quality album that will prove the "music strong" modifier.
