BOBBY 1ST MINI [ROBERT] BOBBY携《ROBERT》回归，金知元将自己完整呈现了出来。这张专辑收录的4首歌曲彷佛就是BOBBY的人生曲线。 BOBBY通过主打歌《f》摆脱压抑和煤气灯效应，向大众展示真正的自己。其后的《hercules!》用DnB体裁所具有的爆发性能量发出咆哮 。 接着，借画出自己的《why stop now》以Boom Bap和 Rock Sound强烈地传达了「要永远活出自我 」的信息。 还有，表达了金知元日后将摆脱周遭的顾虑和担忧，大胆帅气地飞翔的《새(sae)》。 1. f Lyrics by BOBBY Composed by BOBBY, THE PROOF Arranged by THE PROOF 2. hercules!
