In this paper we first present a simple supersymmetric model for a free particle on a circle with point-like interactions that exhibits $\\mathscr{N} = 2$ supersymmetry and doubly degenerate energy levels. We then show that Berry's connection in this model is given by the Wu-Yang-like magnetic monopole in SU(2) Yang-Mills gauge theory.
