In this work we extend the SM by introducing only exotic scalars and leptons and show that within the reasonable error limits, both the observed anomalies in R(D(*)) and RK(*) can be explained along with satisfying all the constrains from nuetral meson oscillations, precision Z-pole data etc. In a trivial extension of our model with addition of three heavy right handed neutrinos, explaining the small masses of neutrinos and generation of Baryon excess via leptogenesis is possible as well. The disagreement between SM prediction and experimental data in muon (g-2) measurements can be reduced from 3.6σ to around 2σ in this model. Also our model has enough new particles for the scalar singlet DM to interact and generate enough annihilation to avoid over abundance problem (exotic portal), unlike the SM Higgs portal which has been ruled out.
