  We propose a predictive inert 2 Higgs doublet model, where the Standard Model
(SM) symmetry is extended by $S_{3}\otimes Z_{2}\otimes Z_{12}$ and the field
content is enlarged by extra scalar fields, charged exotic fermions and two
heavy right-handed Majorana neutrinos. The charged exotic fermions generate a
nontrivial quark mixing and provide one-loop-level masses for the first- and
second-generation charged fermions. The masses of the light active neutrinos
are generated from a one loop-level radiative seesaw mechanism. Our model
successfully explains the observed SM fermion mass and mixing pattern.
