We discuss two models which are part of a class providing common explanation for lepton flavor universality violation in $b \to s l^+ l^- $ decays, the dark matter (DM) problem and muon $(g-2)$ anomaly. The $B$ meson decays anomalies explained by additional one-loop diagrams with DM candidates. have one extra fermion field scalar fields relative to Standard Model (SM). $SU(3)$ quantum numbers fixed interaction SM fermions new Yukawa Lagrangian that connects visible sectors. compare models, where is singlet scalars doublets under $SU(2)_L$ another doublet singlets $SU(2)_L$. conclude both can explain all physics phenomena simultaneously, while satisfying other constraints. However, there crucial differences between how constraints affect leading noticeable difference allowed mass range.
