The purpose of this study is to analyze how 'inner regeneration', the subject of the researcher's work ｢Full Bloom｣, in which the existential identity of human beings is reborn, is expressed. Using literature research and practice-based research methods, the study focuses on analyzing how the theme of the work is visualized through movements. In response to the death of the researcher’s former teacher, the work ｢Full Bloom｣was created. The work has a future-oriented story that paradoxically emphasizes the feeling of ‘being alive’in the present moment, the privilege that only human beings can have. As a result of this study, first, based on the researcher’s actual experience and“Sanogugut,”the theme of the work that combines practice and theory was extracted. Second, a movement technique unique to this work was created to convey the theme. Third, a unified context of the theme was presented with a directing technique that embraces the consensus of each art component. This study presents a choreographic work that delivers the message of an internal crisis that anyone can experience. The study is important to show that choreography can serve as a medium to express one’s inner self and existential identity as an artistic value.
