  We present a model based on $S_1$ scalar leptoquarks to solve the tension
observed in the recently proposed non-leptonic optimized observables $L_{K^{*}
\bar{K}^{*}}$ and $L_{K \bar{K}}$. These observables are constructed as ratios
of U-spin related decays based on $B_{d,s}^0\rightarrow {K^{(*)0}\bar
K^{(*)0}}$. The model gives a one-loop contribution to the Wilson coefficient
of the chromomagnetic dipole operator needed to explain the tension in both
non-leptonic observables, while naturally avoiding large contributions to the
corresponding electromagnetic dipoles. The necessary chiral enhancement comes
from an $O(1)$ Yukawa coupling with a TeV-scale right-handed neutrino running
in the loop. We endow the model with a $U(2)$ flavor symmetry, necessary to
protect light-family flavor observables that otherwise would be in tension.
Furthermore, we show that the same $S_1$ scalar leptoquark is capable of
simultaneously explaining the hints of lepton flavor universality violation
observed in charged-current $B$-decays. The model therefore provides a
potential link between two puzzles in $B$-physics and TeV-scale neutrino mass
generation. Finally, the combined explanation of the $B$-physics puzzles
unavoidably results in an enhancement of $\mathcal{B}(B\rightarrow K \nu \bar
\nu)$, yielding a value close to present bounds.
