In this article, we first introduce the notion of commuting Ricci tensor and pseudo-anti commuting Ricci tensore for Hopf hypersurfaces in the homogeneous nearly K\"{a}hler $\mathbb{S}^3\times\mathbb{S}^3$ and prove that the mean curvature of hypersurface is constant under certain assumptions. Next, we prove the nonexistence of Ricci soliton on Hopf hypersurface
with potential Reeb vector field, which improves a result of Hu-Moruzb-Vranckenc-Yao in \cite{HMVY}.

Keywords: nearly K\"ahler $\mathbb{S}^3\times\mathbb{S}^3$; Hopf hypersurface; commuting Ricci tensor; pseudo-anti commuting Ricci tensor; Ricci soliton.
