The song "Bad Boy" by ERNEST is about a wild and reckless guy who falls in love with a good girl. The protagonist acknowledges his wild nature and the risks he takes in life, but he willingly changes his ways for the girl he loves. The lyrics mention how the protagonist laid down everything for the girl, only keeping his necklace and shoes. Despite the girl having a "little devil" inside, the protagonist still feels drawn to her and senses her fiery personality. The chorus of the song is an invitation for the girl to come over and let the protagonist hold her. He compares himself to Jay-Z (Hova) and the girl to Beyoncé, highlighting their chemistry and compatibility. The protagonist promises to love and show the girl that his love can transform a bad boy into a good man. Throughout the song, the protagonist reveals his infatuation and obsession with the girl. He proclaims himself a "sucker" for her and declares that her affection and kisses drive him crazy. He describes her as the source of his addiction, and when they are together, he feels like he loses his rationality. The bridge part of the song repeats the idea of the protagonist losing control when he is with the girl, emphasizing their intense physical connection. He states he can pleasure her slowly or with intense passion. In the end, the song reiterates the invitation for the girl to come over and be held by the protagonist. It echoes the earlier sentiment that the girl's love has the power to turn a bad boy into a good man.
