This production builds upon the Open Call performance piece "Connection" from the 2023 Want to Dance Festival. Starting with the two sisters, the creation focuses on three dimensions: Replace, Reaction, and Reflection, presenting the inherent connection between sisters. "Connection" invites choreographer Yang Jimmin to further explore the theme of "tacit understanding". Beyond replicating physical movements, the piece delves into how to embody the intangible sense of connection and interpret this sense of "understanding". In this extended performance, the exploration continues without relying on musical beats or visuals. Instead, it relies on the dancers' perception of each other to explore the different possibilities of the two dancers' bodies. It aims to open up their awareness of the surroundings and engage in a dialogue through body language with each other and the audience. "Synergy", the collaborative and enhancing effect, is manifested through the tension, pulling, execution of symmetrical and sequential movements between the two dancers. These elements elevate the energy in the performance beyond that of two individuals, creating a dynamic akin to martial arts films. The dancers' rhythmic breathing, gaze, expressive hair movements, and body language showcase the explosive connection between sisters to the audience.
