Following a series of video teasers for each member, "Bluetory" and its lead single "I'm a Loner" were concurrently released. CNBLUE was met with immediate commercial success; the mini-album topped the Gaon Music Chart for two consecutive weeks, and "I'm a Loner" peaked at number two on the Gaon Digital Chart. The latter earned the quartet two music show wins, the first being on "Music Bank" two weeks into its debut.
