Performing the semiclassical approximation, we obtain a set of two nonlinear coupled differential equations describing the time evolution of intracavity fields. These coupled equations are able to explain the experimentally-observed light non-reciprocity [Peng {\\em et al.}, Nature Physics {\\bf 10}, 394 (2014), Chang {\\em et al.}, Nature Photonics {\\bf 8}, 524 (2014)].
