In this paper, we show that a scalar field in such a hidden sector generically couples to the quadratic curvature via dimension five operators, i.e., $\\phi R^2$, $\\phi R^{\\mu\\nu} R_{\\mu\\nu}$, $\\phi R_{\\mu\\nu\\rho\\sigma} R^{\\mu\\nu\\rho\\sigma}$, $\\phi R_{\\mu\\nu\\rho\\sigma} \\tilde R^{\\mu\\nu\\rho\\sigma}$, because they can emerge if there exist particles heavier than it.
