The concept of $\check{\text{C}}$ech fuzzy soft bi-closure space ($ \check{\text{C}} $fs bi-csp) $\left(\mathcal{U}, \mathcal{L}_{1}, \mathcal{L}_{2}, S\right)$ is initiated and studied by the authors in \cite{6}. The notion of pairwise fuzzy soft separated sets in $ \check{\text{C}} $fs bi-csp is defined in this study, and various features of this notion are proved. Then, we introduce and investigate the concept of connectedness in both $ \check{\text{C}} $fs bi-csps and its associated fuzzy soft bitopological spaces utilizing the concept of pairwise fuzzy soft separated sets. Furthermore, the concept of pairwise feebly connected is introduced, and the relationship between pairwise connected and pairwise feebly connected is discussed. Finally, we provide various instances to further explain our findings.
